	Purpose
		The CUGDropListType is the standard droplist cell type used
		in the Ultimate Grid.  This cell type uses the string stored
		in the 'label' portion of a given cell (set with SetLabelText)
		to populate the drop list.

		Note: In order to make sure that the items in the list are
		shown properly please make sure that each item is separated
		with a new line character (\n).

	Details
		Droplist extended styles
			UGCT_DROPLISTHIDEBUTTON	- the droplist button will only be shown
									  on current cells.  This style allows the
									  grid view not to be overly crowded with
									  droplist buttons keeping the view clean

		Droplist OnCellTypeNotify notifications
			UGCT_DROPLISTSTART		- this notification indicates that the user
									  decided to show the droplist.  This is the
									  final place where the items in the list
									  can be edited or added.
									  The 'param' parameter of this notification
									  contains a CStringList for the items to be
									  shown in the droplist. This list can be modified.
			UGCT_DROPLISTSELECT		- this notification indicates that the user
									  has selected an item in the droplist, 
									  in this notification you are presented with
									  the value that the user selected in the list.
									  The 'param' paramenter contains the a CString
									  pointer of the selected item.
			UGCT_DROPLISTSELECTEX	- this notification is identical to the
									  UGCT_DROPLISTSELECT with one exception, it
									  provides you with the index of the item selected.
									  The 'param' paramenter contains the index of 
									  the selected item.
			UGCT_DROPLISTPOSTSELECT - this notification will be sent after the user's
									  selection was successfuly saved in a cell.
