 +* Added `Io.requiresVersion(Object)` to allow graph providers a way to check 
the `Io` type and version being constructed.
 +* Defaulted `IoCore.gryo()` and `IoCore.graphson()` to both use their 3.0 
formats which means that `` will use those by default.
 +* Bumped Neo4j 3.2.3

  * Added the "Kitchen Sink" test data set.
  * Fixed a bug in `NumberHelper` that led to wrong min/max results if numbers 
exceeded the Integer limits.
  * Delayed setting of the request identifier until `RequestMessage` 
construction by the builder.
 +* `ReferenceElement` avoids `UnsupportedOperationException` handling in 
construction thus improving performance.
+ * Improved error messaging for failed serialization and deserialization of 
request/response messages.
  * Removed hardcoded expectation in metrics serialization test suite as 
different providers may have different outputs.
  * Added `IndexedTraverserSet` which indexes on the value of a `Traverser` 
thus improving performance when used.
  * Utilized `IndexedTraverserSet` in `TraversalVertexProgram` to avoid extra 
iteration when doing `Vertex` lookups.
