This is just adding spark-hpcc:master source code to the hpcc4j/spark-hpcc directory. Working on fixing the pom and getting local builds working in a second pull request for HPCC4J-673

@Michael-Gardner Looks good. However, we realized this is a great opportunity to remove the top-level DataAccess directory. Can we move everything up a level and remove 'DataAccess'?

@jpmcmu what do you think about the /Examples folder? Where could we put that?

[Michael-Gardner]

Agreed. My 673 PR moves the code from spark-hpcc/DataAccess over to spark-hpcc with examples alongside. Then fixes all the poms so that spark-hpcc is a module of the top level poms project.

@rpastrana @Michael-Gardner I think the Examples folder can hang out in the Spark-HPCC folder for now. If we need to move it later that will be easy todo
