When passing an existing neo4j graph into Pacer:
I get an undefined variable or method exception for graph. It looks like the scope of the graph variable is only within the if-check for when path_or_graph is a String. My change is to simply remove the reference to graph and use neo.new directly.
Removed reference to graph when path_or_graph is not a String.
I could use this change as well. If you could submit to rubygems, I'd really appreciate it.
Thanks, and great work!
