Changed to version 2.0.1, to match the Neo4J version used.
Removed dead stores to a local instance, when the test only calls a
static method (which does not reference any internal fields)
Made changes to Config to eliminate dodgy coding practice of writing to a public static field.  Yes, this required lots of code changes elsewhere (through multiple levels), but it bring the the surface problems in the overall code architecture of the batch importer.  The greatest code quality improvements come from the changes that hurt the most at first--only then can you understand the true nature of what should have been done, instead of prolonging substandard practices.
