ManageableCollectionUtil should not throw "unsupported" JcrMapping exception
----------------------------------------------------------------------------

                 Key: GRFT-99
                 URL: http://issues.apache.org/jira/browse/GRFT-99
             Project: Graffito
          Issue Type: Improvement
          Components: JCR-Mapping
    Affects Versions: 1.0-a1-dev
         Environment: All
            Reporter: Dan Connelly


Many times, the object model'd code cannot be altered for ocm.

To avoid the "unsupported" exception in almost all such cases, use a delegating wrapper class
to encapsulate a Collection.    The wrapper class implements MaangeableCollection.

Since delegation is a performance hit, make the test below the last resort for *object*  conversion
in the method:
public static ManageableCollection getManageableCollection(Object object) 

Proposed "catchall" test and program action:

            if (object instanceof Collection) {
                return new ManageableCollectionImpl((Collection)object);
            }
