> PeriodicGraphCheckpointer was introduced for Latent Dirichlet Allocation (LDA), but it could be generalized to work with both Graphs and RDDs.  It should be generalized and moved out of MLlib.
> (For those who are not familiar with it, it tries to automatically handle persisting/unpersisting and checkpointing/removing checkpoint files in a lineage of Graphs.)
> A generalized version might be immediately useful for:
> * RandomForest
> * Streaming
> * GLMs
