[Deliver #106712166] - Paging Functionality

[sethdenner]

Unfortunately this feature will not work out of the box. It will require your django models to inherit from djangocassandra.db.models.ColumnFamilyModel which has a custom manager/queryset which has the paging method attached to it (model.objects.next())

• Impelemented a ColumnFamilyModel class that your cassandra Models should inherit from.
• Impelemented a QuerySet method (djangocassandra.db.query.QuerySet) which has a pagination method called next()
• Implemented a ColumnFamilyModelManager class that utilizes the pagination enabled QuerySet
• Fixed a bug in the database backend compiler.py where query limit statement was not being applied.

hmm, not sure why TravisCI failed but here's the line to invoke the test for this feature: nosetests tests.test_queries:ColumnFamilyModelPagingQueryTestCase.test_paged_query
