- State changed from “new” to “resolved”
(from [7437525af81dfc6922c02d81c20deadcdb82a6b8]) Counting number of nodes is not correct after delete closes #178
Notice the bug fix is done in neo4j-wrapper: https://github.com/andreasronge/neo4j-wrapper/commit/1a1b861f6020ed...
The same issue as #187

Neo4j.rb is a graph database framework for JRuby.
It provides:
* Mapping of ruby objects to nodes in networks rather than in tables.
* Storage of ruby object to a file system.
* Fast traversal of relationships between nodes in a hugh node space.
* Transaction with rollbacks support.
* Indexing and quering of ruby objects.
* Integration with Rails
