Addressed a bunch of things so that the ListComponent, Material, and
Form would play well with the XMLPersistenceProvider and tested it in
ICE. Fixed a small bug in the ICEFormEditor where I forgot to updated
the component map to handle the visitation. Fixed some small bugs and
documentation issues with the Reflectivity Model.

The commit won't build at the moment because I haven't updated the
Reflectivity Model tests. That's the beauty of a branch though!
