> From StoreFile down to HFile, we currently use a boolean argument for each of 
> the various block cache configuration parameters that exist.  The number of 
> parameters is going to continue to increase as we look at compressed cache, 
> delta encoding, and more specific L1/L2 configuration.  Every new config 
> currently requires changing many constructors because it introduces a new 
> boolean.
> We should move everything into a single class so that modifications are much 
> less disruptive.
