adding graphity to the domain examples
Bump version to 1.9
Update instructions following the comment http://docs.neo4j.org/chunked/snapshot/server-installation.html#comment-565895701
SymbolTable is dead. Long live SymbolTable!

This is a major refactoring of the type system in Cypher.
Changed transaction taking around unique indexes

It will open a transaction as late as possible, after checking if
the entity exists in an index.
Deprecates the Reference Node

Adds @Depracated on GraphDatabaseService#getReferenceNode() and corresponding method in BatchInserter
Removes usage of the reference node in test cases that end up in the manual
Notes usage of the reference node in the ReST API for later removal
Changelog entry

Leaves usage of reference node in the shell. It is a larger change that needs some thought.
