stuck in traverser sacks hell all day long. sooooo painful. but out of it with docs, stoked.
minor nothing tweak.
tweaks to sack section.
Add some notes about expected state of Gremlin Console #354
Add fix and test for plugin loading in sessions for Gremlin Server.
Fix code examples for GraphStrategy #357
added gremlin-dashboard image.
Add docs for graph Feature  #317
Merge branch 'master' of github.com:tinkerpop/tinkerpop3
Update the number of suites

Stinks that this is hardcoded, but there's no dependency on gremlin-tests here to know the number of available tests.
Correct docs in example around describeGraph.
Turn on a couple extra tests around strategy wrapping.
Uncommented VertexProgram.getMessageCombiner(). TraversalVertexProgram now makes use of TraverserSet messages to allow for combining when messages to a vertex are not necessarily to the vertex, but also to its edges,properties,etc. Uncommented TinkerGraphComputer's message combiner usage. Added GiraphMessageCombiner to wrap a TP3 message combiner appropriately. MessageType.Local only supports M->M. No more M1->M2 as edge modulation should not change the message class, only modulate it.
removed 'deep reference' feature in GraphComputer/VertexProgram.
renamed MessageType to MessageScope. Added VertexProgram.getMessageScopes(). Tweaked up PageRankVertexProgram and PeerPressureVertexProgram to get edge counts via message passing. Fixed a edgeFunction bug in GiraphGraphComputer. Fixed up StringFactory for VertexProgram and MapReducers that don't have an internalString.
minor JavaDoc tweaks and variable finals.
added SumStep, SumMapReduce, and generalized Operator to support Object so you can sum, min sets. Added more test cases to SackTest.
Correct bad label in docs.
Document BatchGraph #366
Fixed problem serializing Property on Edge for GraphSON #367
