Added py2neo 3 support by veleritas . See 4 6 8.
Change default queue sizes in neo4j importing for speed improvement. See 5. Thanks veleritas.
Add `n_nodes` and `n_nodes` attributes that store the total number of nodes and edges in the graph.
This version has a malformated description on PyPI, hence users are recommend to use v0.2.3 instead.
