Example with the Movie database

Hi everyone!

I finally made the neo4r movie database example, I didn't follow the neo4j example because it didn't cover the main functions of the neo4r package. Also, there are some issues to fix.

Anyway, I prefer to wait for revision to merge in the repository but if anyone wants to see, it is indeed a working example: https://github.com/neo4j-examples/movies-rstats-neo4r/pull/1

Let me know your thoughts!
