Merge pull request #1 from deflaux/master

An initial stab at an RDD for Variant Store.
@cassiedoll, Ok, so it looks it might be possible to get source for google-api-java-client.  Why not just fix it and recompile it afterwards?  Otherwise why not just extend the classes in the jar using a new name GACall or GAVariant and then use them instead.  If you can become one of the members or co-owners for that project in order to request an update, that might speed up some things.  There are probably other approaches, but the above seem like a reasonable start.
