//========= Copyright � 1996-2005, Valve Corporation, All rights reserved. ============//
//
// Purpose: Implements a dialog for editing the input/output connections of a
//			list of entities. The connections are displayed in a grid control,
//			each row of the grid control representing a connection that is
//			common to all entities being edited. For example, given these two ents:
//
//			Button01
//				OnDamaged Sound01 PlaySound 0 0
//				OnPressed Door01 Open 0 0
//
//			Button02
//				OnPressed Door01 Open 0 0
//
//			If these two entities were selected, the grid control would show:
//
//				OnPressed Door01 Open 0 0
//
//			because it is the only connection that is common to both entities.
//			Editing an entry in the grid control modifies the corresponding 
//			connection in all selected entities.
//
// TODO: persist sort column index, sort directions, and column sizes
// TODO: implement an external mode, where the grid shows all connections to unselected ents
