Fix broken test as ids were not being properly set for Neo4j.
Merge remote-tracking branch 'origin/master'
added hadoop-job.xml as that is required for standalone submission of Giraph-Gremlin jobs. Provide a fast fail if input path for GiraphGraphComputer doesn't exist.
sort order on methods from TraversalSourceGenerator so touches dont happen. Hope this works.

Neo4j now passes the SubgraphStrategy test #40

Fixed the problem but also modified tests and subgraph semantics.  Changes were made more or less in line with what was recommended by @MMcM  Still need to clean up code here a bit.
wow. was in Giraph-hell for a long long time.... cant believe I came out. Doc updates, SugarLoader updates... Added static vs. dynamic GroovyScriptEngine loading for the GLambda series.
GraphStep is suuuuuuper simple now that StartStep is a SideEffectStep. Updated accordingly throughout TinkerGraph, Neo4j, and Giraph.
