* TActiveTemplateColumn class
*
* TActiveTemplateColumn customizes the layout of controls in the column with templates.
* In particular, you can specify {@link setItemTemplate ItemTemplate},
* {@link setEditItemTemplate EditItemTemplate}, {@link setHeaderTemplate HeaderTemplate}
* and {@link setFooterTemplate FooterTemplate} to customize specific
* type of cells in the column.
*
* This is the active counterpart to the {@link TTemplateColumn} control. For that purpose,
* if sorting is allowed, the header links/buttons are replaced by active controls.
*
* Please refer to the original documentation of the {@link TTemplateColumn} for usage.
