Fixes for backwards compatibility breakage in index batch insertion.
o Updates clirr plugin config in kernel to reflect accepted breaking changes
o Added a BREAKING CHANGE note in the kernel changelog
Use a small graph of actors and movies for example queries.

o This graph is much more meaningful that the abstract graph it replaces.
o We chose to include Martin Sheen and Charlie Sheen because their family
  relationship makes many examples easy that are otherwise difficult in a
  strictly bipartite person/movie graph.
Replace deprecated method.
