[Dev] ItemCollections branch status

[Ted Leung]

Hi folks,

The ItemCollections branch (svn+ssh://svn.osafoundation.org/svn/ 
chandler/branches/ItemCollection_0.6)
now has the set / collection stuff in it.

The collection stuff is in parcels/osaf/contentmodel/Collections.py

and the unit tests are in parcels/osaf/contentmodel/tests/ 
TestCollections.py

I've incorporated Andi's indexing stuff into the Collection API's as  
well.

I think that we should be ready to start integrating this stuff into  
Chandler.    John and Morgen, I'll try to
sync up with each of you tomorrow to figure out how I can best help you.

Ted
