PUBLIC ClearUltraGridColumnEditors (UltraGrid)
Purpose: Clears references to the UltraGrid cells EditorComponent

and cause the grid not to be GC'ed when a Form is closed. Invoked from
the BaseForm:OnFormClosed method

Parameters:
poUltraGrid Infragistics.Win.UltraWinGrid.UltraGrid
The reference to the UltraTree object
