Py2Neo Tutorial: Converting Movie Example

Hello! I made a fun tutorial (largely for my own benefit, to become familiar with the library), as such it may be incorrect, erroneous or be missing obvious information.

Others may find it useful, and correction and improvements (pull requests are very welcome).

I've already said to @technige that in my dreams workings can be added to here: py2neo/notebooks at v4.2 · py2neo-org/py2neo · GitHub

Thanks a lot Elenea, really useful.

Please cross-post to #projects-collaboration

Brilliant, thanks @elena :)
