------------------------------------------------------------------

I'm having some difficulties with Phoenix Spark integration due to dependencies 
and general Scala compiler crap* that I assume will bedevil HBase users once we 
have a Spark integration module as well. I strongly prefer holding spark/scala 
dependencies to one module, which furthermore may be optionally skipped during 
build, for the time being. 

* - Sometimes, if you have an optional dependency (as part of the transitive 
dependency set), Maven+Scala won't pull it in, the Scala compiler with 
synthesize a stub, this isn't sufficient for something, and the compiler will 
NPE. Might come up at any time as the set of transitive dependencies change.
