// Name:			PendingDelta

//
// Description:		This class stores a database delta.  When
//					a game is saved, all the changes to the database
//					are stored in the save game file.  When this
//					file is loaded, these changes are made back to
//					the gameplay database.
//
//					However, the changes are made before the client
//					has had a chance to initialize.  We store off
//					all these changes until then.  When the server
//					learns the player is fully initialized, the 
//					GameplayManager will ask for this list of
//					pending deltas.  It will then send them all
//					to the client.
