CollectionFrom (GeometryCollection <-> Geometry Fields!)

Motivation: We can't use GeometryCollections to do filters, etc in GeoDjango due to incomplete underlying libraries. But with this CollectionFrom field we can get all the benefits of working with GeometryCollections but still query based on points, lines, polys. If you're using GeometryCollectionFields and see this error: DatabaseError: Relate Operation called with a LWGEOMCOLLECTION type. This is unsupported. Then this will probably be helpful for you.
