CollectionModel: want analogue to ListDataModel that can handle removal of items cleanly
----------------------------------------------------------------------------------------

                 URL: https://issues.apache.org/jira/browse/TRINIDAD-114
             Project: MyFaces Trinidad
          Issue Type: New Feature

It would be extremely handy to have an analogue to ListDataModel that can deal with 
adding or removing items (or plain mutations to the list) without getting confused, 
by implementing CollectionModel.getRowKey(). 

I can think of two routes: 
 - A CollectionModel that exposes add/remove and keeps track of 
   row keys, so it doesn't get lost 
 - A CollectionModel that has a "keyProperty" - the name of the object 
   property that is the row key - and uses this to retrieve the row key at all 
   times.
