[1/4] incubator-tinkerpop git commit: The most brutal refactor. There
is no such thing as a TraversalSource.Builder anymore. All there are are
TraversalSources. These are simply a wrapper of a TraversalStrategy and a
Graph. There is no such thing as a Tr

Posted by ok...@apache.org.
The most brutal refactor. There is no such thing as a TraversalSource.Builder anymore. All there are are TraversalSources. These are simply a wrapper of a TraversalStrategy and a Graph. There is no such thing as a TraversalEngine anymore. What was ComputerTraversalEngine is now simply a strategy of TraversalVertexProgramStrategy. There is no such thing as EngineDependentStrategy -- this is simply TraversalVertexProgramStrategy. In short, all there are are Graphs and TraversalStrategies. So so so so so much cleaner. This WILL NOT be backwards compatible for graph system providers. They will need to update their GraphProvider implementations -- two methods changed. Moreover, if they have an XXXStrategy that calls traversal.getEngine().isComputer(), they will need to change that to traversal.getStrategies().onGraphComputer(). Really simple to for them to fix. It took me less a minute to fix up Spark, Giraph, and Neo4j. These changes WILL be backwards compatible for users at the level of
graph.traversal(computer(SparkGraphComputer)) still working (though Depcrecation introduced). The GraphTraversal.Builder will simply turn into a bunch of TravesalSource calls. It is not used outside of this context. This commit is NOT complete and will be completed on the next sprint. Moreover, there are lots of cleanups and JavaDocing that I need to do -- I just don't want to lose this work so pushing.
