TINKERPOP-1878 sparql-gremlin
https://issues.apache.org/jira/browse/TINKERPOP-1878
I think this is ready for review. As an engine it stands on its own pretty
well as our first compiler. Still needs GLV support but personally I don't
think that's a massive problem for getting this onto 3.4.0 - if we had to
release without GLV support I think we could do so. We do need a pattern for
sorting out additional traversal sources in GLVs anyway and I think that's too
different a body of work to place in front of this.

TINKERPOP-1878 Dropped the console app
This allows TinkerGraph to remain a test dependency only and the console
app was more of a test rig than something that a user of this library would
use, so it seemed like something that could be dropped.

TINKERPOP-1878 Minor javadoc and code cleanup

TINKERPOP-1878 sparql() step works over remoting
At this point it is only tested to work with Gryo 3.0. Fixed a bug with how
dynamic gryo registrations work - they failed if you didn't have a specific
serializer specified. Introduced a bit of a hack to make SparqlTraversalSource
behave like a GraphTraversalSource and thus more cleanly follow the DSL
pattern. Not sure if that's a great approach yet or not, but it seems harmless
at this point.

TINKERPOP-1878 Major refactoring of sparql-gremlin classes
Renamed the "compiler" to a "transpiler" since it's really transforming
sparql to a language of a similar level of abstraction in Gremlin. Lots of code
reformatting and dead code pruning.

TINKERPOP-1878 Added a test for ordering and corrected some problems in
logic
Ordering didn't work - at least not completely. The test, as it is written
in this commit, that failed to sort properly. Changed the logic for ordering to
track all of the keys specified to ORDER with their appropriate ASC/DESC
operators and added all of them to the traversal.

TINKERPOP-1878 Test for FILTER
Also fixed how the SparqlStrategy was being added to the
TraversalStrategies in SparqlTraversalSource...it was adding it globally and
all spawned TraversalSource instances were getting that strategy.

TINKERPOP-1878 Renamed "transpiler" to "compiler"
Since we're converting to Gremlin bytecode it's really compiling and not
transpiling (as in converting to other source code)
