For example, #0000ff value is rendered as blue, because the blue component is set to its highest value (ff) and the others are set to 00.
  *   Hexadecimal colors with transparency, is specified with: #RRGGBBAA, where AA (alpha) value must be between 00 and FF. For example, #0000ff80 defines a semi-transparent blue.
  *   RGB colors, is specified with the RGB(red, green, blue) function. Each parameter (red, green, and blue) defines the intensity of the color and can be an integer between 0 and 255. For example, rgb(0,0,255) defines the blue color.
  *   RGBA colors, are an extension of RGB color values with an alpha channel as RGBA(red, green, blue, alpha) function, where the alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, rgba(0,0,255,0.5) defines a semi-transparent blue.
  *   HSL colors, is specified with the HSL(hue, saturation, lightness) function, where hue is a degree on the color wheel (from 0 to 360) - 0 (or 360) is red, 120 is green, 240 is blue. saturation is a percentage value; 0% means a shade of gray and 100% is the full color. lightness is also a percentage; 0% is black, 100% is white. HSL stands for hue, saturation, and lightness - and represents a cylindrical-coordinate representation of colors. For example, hsl(240, 100%, 50%) defines the blue color.
  *   HSLA colors, are an extension of HSL color values with an alpha channel - which specifies the opacity of the object as HSLA(hue, saturation, lightness, alpha) function, where alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque). For example, hsla(240, 100%, 50%,0.5) defines a semi-transparent blue.
  *   Predefined/Cross-browser color names, 140 color names are predefined in the HTML and CSS color specification. For example, blue defines the blue color.
  * 
  * @type {(string|object)}
  * @example
  * 
  *   null {null}, the tfi field is ignored
  *   "bold monospace 16" {string}, defines Monospace font of 16px height, bold
  *   {bold: true, fontName: "monospace", fontSize: 16} {object}, defines Monospace font of 16px height, bold

   *      [header], specifies that the "scroll" is possible once the user clicks the header of the view
   *    "zoom", zooms the control's content at dragging-point.
   *    "fit", fits the drag-area into the control's client area.
   *    "select", selects items by drag
   *    "edit", edits the cell being clicked (not available if the control is read-only)
   *    "item-drag", moves items by drag (not available if the control is read-only). The "item-drag" action allows flags such as:
   *      [position], The item can be dragged from a position to another, but not outside of its group. If your items are arranged as a flat list, no hierarchy, this option can be used to allow the user change the item's position at runtime by drag and drop. This option does not change the parent of any dragged item.
   *      [keepIndent], The item can be dragged to any position or to any parent, while the dragging object keeps its indentation. This option can be used to allow the user change the item's position at runtime by drag and drop. In the same time, the parent's item could be changed but keeping the item's indentation.
   *      [any], The item can be dragged to any position or to any parent, with no restriction (by default, if no flag is present).
   *    "item-resize", resize items by drag (available only if the control's readOnly property is false, and item's allowSizing field is true). The "item-resize" action allows flags such as:
   *      [all], specifies that once an item gets resized all resizable-items get resized (changes the control's defaultItemHeight property). If the [all] flag is missing, only the item (or all selected items) get resized
   *    "column-resize", resizes columns by drag. If "column-resize" action has no flags it indicates that resizing is possible in view and header as well (available only if the control's readOnly property is false, and the column's allowSizing field is true). The "column-resize" action allows flags such as:
   *      [view], specifies that the "column-resize" operation is possible in the view
   *      [header], specifies that the "column-resize" operation is possible in the header of the view
   *    "column-drag", drags the column to a new position (not available if the control is read-only)
   * 
   *  "shortcut", defines the event's button or/and the modifier-keys that are required to perform the action. The "shortcut" is a combination of none, one or more of the following values:
   * 
   *    "Shift", indicates that the SHIFT key is pressed
   *    "Ctrl" or "Control", indicates that the CTRL key is pressed
   *    "Alt" or "Menu", indicates that the ALT key is pressed
   *    "Meta" , indicates that the META key is pressed
   *    "LButton", specifies that the mouse's left-button is pressed
   *    "RButton", specifies that the mouse's right-button is pressed
   *    "MButton", specifies that the mouse's middle/wheel-button is pressed
   *    "Long", specifies that the action requires a "long" click or touch before it begins
   *    "Double", specifies that the action requires a "double" click before it begins (this flag is available for non-dragable actions only such as "edit")
   *    "+", indicates AND between values
   * 
   * @example
   * 
   *  null {null}, indicates the control's default allowActions value
   *  "" {string}, specifies that no operation is allowed once the user clicks or touches the control
   *  "scroll" {string}, specifies that only "scroll" operation is allowed, no matter of the event's button or modifier-keys is pressed.
   *  "column-resize[view](LButton)" {string}, allows resizing the columns (inside the view), while pressing the mouse's left-button only
   *  "column-drag(Shift+LButton),item-drag,scroll" {string}, indicates that dragging a column is possible only if the user presses the mouse's left-button while SHIFT key is pressed, and "item-drag" or "scroll" is possible no matter of the event's button or modifier-keys in this order (if one operation is not possible, the next one is performed).

   *        sum, performs addition of values
   *        min, retrieves the minimum value
   *        max, retrieves the maximum value
   *        count, counts the number of items
   *        avg, calculates the average of values

   *        a number expression that specifies the index of the item being referred
   *        all, indicates all items, so the formula is being applied to all items. The direction has no effect

   * 
   *      not-sortable items. The SortableItem property specifies whether the item can be sorted ( a sortable item can change its position after sorting, while a not-sortable item keeps its position after sorting. 
   *      not-selectable items. The SelectableItem property specifies whether the user can selects/focus the specified item.
   *      divider items. The ItemDivider property specifies whether the item displays a single cell, instead displaying whole cells.
   * 
   *    In conclusion, aggregate functions counts ONLY items that are sortable, selectable and not a divider-item.
   * 
   *    For instance:

   *      "get(`count(current,all,1)`)", gets the count of all child-items (implies recursively child items)
   *      "get(`count(current,rec,1)`)", counts the number of leaf items ( a leaf item is an item with no child items ).
   *      "get(`sum(current,dir,%1 ? 1 : 0)`)", counts the number of child-items that have not-empty cells within the second-column
   *      "get(`sum(current,dir,value)`)", gets the total of values of child-items (direct descendent) within the same column
   *      "get(`sum(all,rec,value)`)", gets the total of values of leaf-items within the same column
   *      "get(`sum(parent,dir,dbl(%1) + dbl(%2))`)", gets the addition of all cells in the second (%1) and third (%2) column that are directly descendent of the parent item (sibling). 
   * 
   *  The format-expression supports the following binary-operators:
   * 
   *    0 index `format`, gets the index of the item (0-based). The first added item has the index 0, the second added item has the index 1, and so on. The index of the item remains the same even if the order of the items is changed by sorting or grouping ( "1 index ``", gets the index of the item starting from 1 )
   *    0 rindex `delimiter|format|format|...`, returns the recursive-index of the item ("1 rindex `.|A-Z`", returns values as A, A.1, A.2, B, ...)
   *    0 pos `format`, returns the relative position of the item (the position within the parent's children collection) ( "1 pos ``", returns the position of the item (1-based) within the parent's child items collection )
   *    0 rpos `delimiter|format|format|...`, returns the recursive relative-position of the item (the position within the parent's children collection) ( "1 rpos `.|A-Z`", returns values as A, A.1, A.2, B, ... )
   *    0 opos `format`, returns the relative old position of the item (the position within the parent's children collection) ( "1 opos ``", returns the position of the item (1-based) within the parent's child items collection )
   *    0 ropos `delimiter|format|format|...`, returns the recursive relative-old-position of the item (the position within the parent's children collection) ( "1 ropos `.|A-Z`", returns values as A, A.1, A.2, B, ... )
   *    0 apos `format`, returns the absolute position of the item (the position from the first visible item) ( "1 apos ``", gets absolute position of the item )
   *    0 rapos `delimiter|format|format|...`, returns the recursive absolute-position of the item (the position from the first visible item) ( "1 rapos `.|A-Z`", returns values as A, A.1, A.2, B, ... )

For instance, "upper(value)" displays the caption in uppercase or "value replace `<b>` with `<fgcolor=808080>` replace `</b>` with `</fgcolor>`" displays the column's name with a different foreground color. 
   *  "itemcount", returns the total number of items as indicated by ItemCount property. At runtime the itemcount is a positive integer that indicates the count of all items. For instance, "value + `<r><fgcolor=808080>Total: ` + itemcount" includes in the filter bar the number of items aligned to the right.
   *  "visibleitemcount", returns the number of visible items as indicated by VisibleItemCount property. At runtime, the visibleitemcount is a positive integer if no filter is applied, and negative if a filter is applied. If positive, it indicates the number of visible items. The visible items does not include child items of a collapsed item. If negative, a filter is applied, and the absolute value minus one, indicates the number of visible items after filter is applied. 0 indicates no visible items, while -1 indicates that a filter is applied, but no item matches the filter criteria.

   *  "matchitemcount", returns the number of items that match the filter as indicated by MatchItemCount property. At runtime, the matchitemcount is a positive integer if no filter is applied, and negative if a filter is applied. If positive, it indicates the number of items within the control (ItemCount property). If negative, a filter is applied, and the absolute value minus one, indicates the number of matching items after filter is applied. A matching item includes its parent items, if the control's FilterInclude property allows including child items.  0 indicates no visible items, while -1 indicates that a filter is applied, but no item matches the filter criteria. For instance, "value + `<r><fgcolor=808080>` + ( matchitemcount < 0 ? ( `Result: ` + ( abs(matchitemcount) - 1 ) ) : ( `Visible: ` + matchitemcount ) )" includes "Visible: " plus number of visible items, if no filter is applied or "Result: " plus number of macthing items, if filter is applied, aligned to the right
   *  "leafitemcount", returns the number of leaf-items. A leaf item is an item with no child items. At runtime, the leafitemcount is a positive number that computes the number of leaf-items ( expanded or collapsed ). For instance, the "value + `<r><fgcolor=808080><font ;6>` + leafitemcount" displays the number of leaf-items aligned to the right with a different font and foreground color.
   *  "promptpattern", returns the pattern in the filter bar's prompt, as a string. The FilterBarPromptPattern specifies the pattern for the filter prompt. The control's filter bar prompt is visible, if the  exFilterBarPromptVisible flag is included in the FilterBarPromptVisible property.
   *  "available", returns the list of columns that are not currently part of the control's filter, but are available to be filtered. A column is available to be filtered, if the DisplayFilterButton property of the Column object, is True. At runtime, the available keyword may return a string such as "<fgcolor=C0C0C0>[<s>OrderDate</s>]<fgcolor> </fgcolor>[<s>RequiredDate</s>]<fgcolor> </fgcolor>[<s>ShippedDate</s>]<fgcolor> </fgcolor>[<s>ShipCountry</s>]<fgcolor> </fgcolor>[<s>Select</s>]</fgcolor>", so the control automatically applies HTML format, which you can change it. For instance, "value + ` ` + available", displays the current filter, including all available columns to be filtered. For instance, the "value + `<r>` + available replace `C0C0C0` with `FF0000`" displays the available columns aligned to the right with a different foreground color.
   *  "allui", returns the list of columns that are part of the current filter and available columns to be filtered. A column is available to be filtered, if the DisplayFilterButton property of the Column object, is True. At runtime, the allui keyword may return a string such as "[<b>EmployeeID</b>] = '4| 5| 6'<fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>OrderDate</s>]</fgcolor><fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>RequiredDate</s>]</fgcolor><fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>ShippedDate</s>]</fgcolor><fgcolor> </fgcolor>[<b>ShipVia</b>] = <img>1</img><fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>ShipCountry</s>]</fgcolor><fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>Select</s>]</fgcolor>", so the control automatically applies HTML format, which you can change it. For instance, "allui", displays the current filter, including all available columns to be filtered. For instance, the "((allui + `<fgcolor=808080>` + ( matchitemcount < 0 ? ( ( len(allui) ? `` : `` ) + `<r>` + abs(matchitemcount + 1) + ` result(s)` ) : (`<r><fgcolor=808080>`+ itemcount + ` item(s)`) )) replace `[<b>` with `<bgcolor=000000><fgcolor=FFFFFF><b> ` replace `</b>]` with ` </b></bgcolor></fgcolor>` replace `[<s>` with `<bgcolor=C0C0C0><fgcolor=FFFFFF> ` replace `</s>]` with ` </bgcolor></fgcolor>` )" displays all available columns to be filtered with different background/foreground colors including the number of items/results
   *  "all", returns the list of all columns ( visible or hidden ) no matter if the DisplayFilterButton property is True or False. At runtime, the all keyword may return a string such as "<fgcolor=C0C0C0>[<s>OrderID</s>]</fgcolor><fgcolor> </fgcolor>[<b>EmployeeID</b>] = '4| 5| 6'<fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>OrderDate</s>]</fgcolor><fgcolor> </fgcolor><fgcolor=C0C0C0>[<s>RequiredDate</s>]</fgcolor><fgcolor>", so the control automatically applies HTML format, which you can change it. For instance, "all", displays the current filter, including all other columns. For instance, the "((all + `<fgcolor=808080>` + ( matchitemcount < 0 ? ( ( len(allui) ? `` : `` ) + `<r>` + abs(matchitemcount + 1) + ` result(s)` ) : (`<r><fgcolor=808080>`+ itemcount + ` item(s)`) )) replace `[<b>` with `<bgcolor=000000><fgcolor=FFFFFF><b> ` replace `</b>]` with ` </b></bgcolor></fgcolor>` replace `[<s>` with `<bgcolor=C0C0C0><fgcolor=FFFFFF> ` replace `</s>]` with ` </bgcolor></fgcolor>` )" displays all columns with different background/foreground colors including the number of items/results

   * @type {string} Specifies the column's filter. The filter depends on the filterType as explained:

   *  filterType = exFilter, the filter field indicates the list (separated by "|" character) of values to filter for. For instance, filter = "Cell A", filters for items with the caption "Cell A", filter = "Cell A|Cell B", filters for items with the caption  "CellA" or "CellB".
   *  filterType = exPattern, the filter field defines the wild-patterns to filter for items (separated by "|" character). A pattern-filter may contain wild card characters like '?' for any single character, '*' for zero or more occurrences of any character, '#' for any digit character. For instance: "A*" filters for items that begins with "A" or "a", "A*|B*" filters for items that starts with "A", "a", "B" or "b".
   *  filterType = exDate, the filter field contains alternative interval-dates to filter for (separated by "|" character). An interval-date could be of "[dateFrom] [to] [dateTo]" or "[operator] date [operator date ...]" format. The "[dateFrom] [to] [dateTo]" format filter for items that fit the interval. For instance: "2/13/2004" filter only for items with the date on 2/13/2004, "2/13/2004 to", filter for items whose date is greater or equal with 2/13/2004, "to 2/13/2004" filter for items with the date less or equal with 2/13/2004. For instance: "2/13/2004 | 2/13/2005 to" filter for items with the date on 2/13/2004 or greater or equal with 2/13/2005. The "operator date [operator date ...]" format  allows to filter using multiple operators as <, <=, =, <>, !=, >= or >. For instance: "> 2/13/2004" filter for items with the date greater than 2/13/2004, "> 2/13/2004 | <= 2/13/2002" filter for dates greater than 2/13/2004 or less or greater than 2/13/2002
   *  filterType = exNumeric, the filter field specifies a list of numeric-rules to filter for (separated by "|" character). The format of filter field is "[operator] number [operator number ...]", which define numeric-rule, where operator is one of <, <=, =, <>, !=, >= or >. For instance, the "> 10" filters for numbers greater than 10, "> 10 < 100" filters for numbers greater than 10 and less than 100, "10|20|>50" filters for items that include 10, 20 or any number greater than 50
   *  filterType = exCheck, the filter field specifies a list of states to filter for (separated by "|" character). The cell's state is "0" (unchecked), "1" (checked) and "2" (partial-checked). For instance: "1" filters for checked items, "1|2" filters for partially and checked items
   *  filterType = exImage, the filter field defines the list of images (separated by "|" character) to filter for. The cell's image property specifies the image of the cell. For instance, "Al" filters for items that displays the "Al" picture/image, "Al|Peggy" filters for items that displays the "Al" or "Peggy" images. The exontrol.HTMLPicture.Add() method adds named images to the control.
   * 
   * The filter field has no effect if the filterType field is exAll, exBlanks or exNonBlanks. The filter is case-sensitive, if the filterType includes the exFilterDoCaseSensitive flag.
   * 
   * @example
   * 
   *  null {null}, clears the column's filter
   *  "" {string}, filters for empty-captions
   *  "Cell A|Cell B" {string}, filters for items that include "Cell A" or "Cell B" within the column

  /**
   * @description The filterType field defines the type of the column's filter.
   * @type {exontrol.Tree.FilterTypeEnum} Indicates the type of the column's filter. 
   * 
   * The exontrol.Tree.FilterTypeEnum type supports the following values and flags:
   * 
   *  exAll (0), no filter is applied
   *  exBlanks (1), includes only blank/empty items (a blank item is an empty item or an item that displays whitespace characters)
   *  exNonBlanks (2), includes only non blank/empty items (a blank item is an empty item or an item that displays whitespace characters)
   *  exPattern (3), includes only items that match the pattern. The Filter property defines the pattern. A pattern may contain the wild card characters '?' for any single character, '*' for zero or more occurrences of any character, '#' for any digit character, and [chars] indicates a group of characters. If any of the *, ?, # or | characters are preceded by a \ ( escape character ) it masks the character itself. Can be combined with exFilterDoCaseSensitive flag
   *  exDate (4), includes only items that fit the date interval. The Filter property of the Column object defines the interval of dates being used to filter items. The interval of dates should be as [dateFrom] to [dateTo]. If the dateFrom value is missing, the control includes only the items before the dateTo date, if the dateTo value is missing, the control includes the items after the dateFrom date. If both dates ( dateFrom and dateTo ) are present, the control includes the items between this interval of dates. For instance, the "2/13/2004 to" includes all items after 2/13/2004 inclusive, or "2/13/2004 to Feb 14 2005" includes all items between 2/13/2004 and 2/14/2004.
   *  exNumeric (5), includes only items of numeric type that check the expression. The expression supports operators like <, <=, =, <>, >= or > and numbers to define rules.  For instance, the "> 10 < 100" filter indicates all numbers greater than 10 and less than 100.
   *  exCheck (6), includes only checked-items, while Filter property is "1" or unchecked-items if Filter is "0"
   *  exImage (10), includes only items that match the images within the Filter property.
   *  exFilter (240), includes only items that match the Filter property. Can be combined with exFilterDoCaseSensitive flag
   *  exFilterDoCaseSensitive (0x100), By default, the column's filter is case-insensitive. Specifies a case-sensitive column's filter. Can be combined with exPattern or exFilter flag
   *  exFilterExclude (0x200), The flag indicates that the Exclude field of the column is checked. The flag indicates that the items that match the filter are excluded from the list.
   * 
   * The filter depends on the filterType as explained:
   * 
   *  filterType = exFilter, the filter field indicates the list (separated by "|" character) of values to filter for. For instance, filter = "Cell A", filters for items with the caption "Cell A", filter = "Cell A|Cell B", filters for items with the caption  "CellA" or "CellB".
   *  filterType = exPattern, the filter field defines the wild-patterns to filter for items (separated by "|" character). A pattern-filter may contain wild card characters like '?' for any single character, '*' for zero or more occurrences of any character, '#' for any digit character. For instance: "A*" filters for items that begins with "A" or "a", "A*|B*" filters for items that starts with "A", "a", "B" or "b".
   *  filterType = exDate, the filter field contains alternative interval-dates to filter for (separated by "|" character). An interval-date could be of "[dateFrom] [to] [dateTo]" or "[operator] date [operator date ...]" format. The "[dateFrom] [to] [dateTo]" format filter for items that fit the interval. For instance: "2/13/2004" filter only for items with the date on 2/13/2004, "2/13/2004 to", filter for items whose date is greater or equal with 2/13/2004, "to 2/13/2004" filter for items with the date less or equal with 2/13/2004. For instance: "2/13/2004 | 2/13/2005 to" filter for items with the date on 2/13/2004 or greater or equal with 2/13/2005. The "operator date [operator date ...]" format  allows to filter using multiple operators as <, <=, =, <>, !=, >= or >. For instance: "> 2/13/2004" filter for items with the date greater than 2/13/2004, "> 2/13/2004 | <= 2/13/2002" filter for dates greater than 2/13/2004 or less or greater than 2/13/2002
   *  filterType = exNumeric, the filter field specifies a list of numeric-rules to filter for (separated by "|" character). The format of filter field is "[operator] number [operator number ...]", which define numeric-rule, where operator is one of <, <=, =, <>, !=, >= or >. For instance, the "> 10" filters for numbers greater than 10, "> 10 < 100" filters for numbers greater than 10 and less than 100, "10|20|>50" filters for items that include 10, 20 or any number greater than 50
   *  filterType = exCheck, the filter field specifies a list of states to filter for (separated by "|" character). The cell's state is "0" (unchecked), "1" (checked) and "2" (partial-checked). For instance: "1" filters for checked items, "1|2" filters for partially and checked items
   *  filterType = exImage, the filter field defines the list of images (separated by "|" character) to filter for. The cell's image property specifies the image of the cell. For instance, "Al" filters for items that displays the "Al" picture/image, "Al|Peggy" filters for items that displays the "Al" or "Peggy" images. The exontrol.HTMLPicture.Add() method adds named images to the control.
   * 
   * The filter field has no effect if the filterType field is exAll, exBlanks or exNonBlanks. The filter is case-sensitive, if the filterType includes the exFilterDoCaseSensitive flag.
   * 
   * @example
   * 
   *  2 or exontrol.Tree.FilterTypeEnum.exNonBlanks {number}, filters for not-blank items (a blank item is an empty item or an item that displays whitespace characters)
   *  6 or exontrol.Tree.FilterTypeEnum.exCheck {number}, filters for checked-items (while filter field is "1") or unchecked-items (while filter field is "0")
   *

   *  exSortItemsDesc (0x10), sorts descending the items of the filter's list. If none of the exSortItemsAsc or exSortItemsDesc is present, the list is built as the items are displayed in the control.

   * @description The format field specifies the expression to format the cell
   * @type {string} Indicates the expression to format the cell
   * 
   *  The format-expression supports the following keywords:
   * 
   *    value, indicates the value of the current cell ( "value/2 format ``", displays half of the value using current regional format )
   *    %0, %1, %2, ... specifies the value of the cell in the column with the index 0, 1 2, ... ( "currency(%0 + %1)", adds the value of first and second cell and displays it as a currency )
   *    %C0, %C1, %C2, ... specifies the caption of the cell, or the string the cell displays in the column with the index 0, 1 2, ... ( "%C0 + %C1", concatenates the caption of first and second cell )
   *    %CD0, %CD1, %CD2, ... specifies the cell's user-date in the column with the index 0, 1 2, ... ( "%CD0 ? value : ``", displays the cell's value only if the cell's data is not empty )
   *    %CS0, %CS1, %CS2, ... specifies the cell's state in the column with the index 0, 1 2, ... ( "(%CS0 ? `<b>` : ``) + value", displays the cell's value in bold only if the first cell is checked )
   * 
   *  The format-expression supports the following unary-operators:
   * 
   *    exp(``), checks whether the item is expanded or collapsed ( "(exp(``) ? `<b>` : ``) + value", shows expanded-items in bold )
   *    get(`aggregate(list,direction,formula)`), summarizes the cell based on "aggregate(list,direction,formula)" syntax, where:
   * 
   *      aggregate, must be one of the following:
   * 
   *        sum, performs addition of values
   *        min, retrieves the minimum value
   *        max, retrieves the maximum value
   *        count, counts the number of items
   *        avg, calculates the average of values
   *        std, gets standard-deviation of numbers
   * 
   *      list, must be one of the following:
   * 
   *        a number expression that specifies the index of the item being referred
   *        all, indicates all items, so the formula is being applied to all items. The direction has no effect
   *        current, refers the current item
   *        parent, refers to the parent item
   *        root, refers to the root item (the root item has no parent items)
   * 
   *      direction, must be one of the following:
   * 
   *        dir, collects only direct descendents (child-items)
   *        rec, collects recursivelly the leaf descendents ( leaf items ). A leaf item is an item with no child items
   *        all, collects all descendents
   * 
   *    Currently, the following items are excluded by aggregate functions:
   * 
   *      not-sortable items. The SortableItem property specifies whether the item can be sorted ( a sortable item can change its position after sorting, while a not-sortable item keeps its position after sorting. 
   *      not-selectable items. The SelectableItem property specifies whether the user can selects/focus the specified item.
   *      divider items. The ItemDivider property specifies whether the item displays a single cell, instead displaying whole cells.
   * 
   *    In conclusion, aggregate functions counts ONLY items that are sortable, selectable and not a divider-item.
   * 
   *    For instance:
   * 
   *      "get(`count(current,dir,1)`)", gets the count of child-items
   *      "get(`count(current,all,1)`)", gets the count of all child-items (implies recursively child items)
   *      "get(`count(current,rec,1)`)", counts the number of leaf items ( a leaf item is an item with no child items ).
   *      "get(`sum(current,dir,%1 ? 1 : 0)`)", counts the number of child-items that have not-empty cells within the second-column
   *      "get(`sum(current,dir,value)`)", gets the total of values of child-items (direct descendent) within the same column
   *      "get(`sum(all,rec,value)`)", gets the total of values of leaf-items within the same column
   *      "get(`sum(parent,dir,dbl(%1) + dbl(%2))`)", gets the addition of all cells in the second (%1) and third (%2) column that are directly descendent of the parent item (sibling). 
   * 
   *  The format-expression supports the following binary-operators:
   * 
   *    0 index `format`, gets the index of the item (0-based). The first added item has the index 0, the second added item has the index 1, and so on. The index of the item remains the same even if the order of the items is changed by sorting or grouping ( "1 index ``", gets the index of the item starting from 1 )
   *    0 rindex `delimiter|format|format|...`, returns the recursive-index of the item ("1 rindex `.|A-Z`", returns values as A, A.1, A.2, B, ...)
   *    0 pos `format`, returns the relative position of the item (the position within the parent's children collection) ( "1 pos ``", returns the position of the item (1-based) within the parent's child items collection )
   *    0 rpos `delimiter|format|format|...`, returns the recursive relative-position of the item (the position within the parent's children collection) ( "1 rpos `.|A-Z`", returns values as A, A.1, A.2, B, ... )
   *    0 opos `format`, returns the relative old position of the item (the position within the parent's children collection) ( "1 opos ``", returns the position of the item (1-based) within the parent's child items collection )
   *    0 ropos `delimiter|format|format|...`, returns the recursive relative-old-position of the item (the position within the parent's children collection) ( "1 ropos `.|A-Z`", returns values as A, A.1, A.2, B, ... )
   *    0 apos `format`, returns the absolute position of the item (the position from the first visible item) ( "1 apos ``", gets absolute position of the item )
   *    0 rapos `delimiter|format|format|...`, returns the recursive absolute-position of the item (the position from the first visible item) ( "1 rapos `.|A-Z`", returns values as A, A.1, A.2, B, ... )
   * 
   *  where:
   * 
   *  `delimiter`, is a character to separated recursive-operators such as "rindex", "rpos", "ropos" and "rapos" 
   *  `format`, is a set of characters to be used for specifying the index
   * 
   * @example
   * 
   *  "value format ``" {string}, shows the cell's value formatted as a number (as in regional settings)
   *  "1 index ``" {string}, gets the index (1-based) of the item
   *  "1 rpos `.|A-Z`" {string}, displays A, B, C for root-items, and A.1, A.2, A.1.1, ... B.1, B.2, ... for child-items
   *  "currency(dbl(%0) + dbl(%1))" {string}, adds columns 0 and 1 and displays the result as currency
