Exporting a Networkx graph as a Cypher query

This little project defines a function that can be used to construct a Cypher query which when executed against a Neo4j database server will store the graph to the server.

Background

• A Graph is an abstract mathematical model composed of Nodes connected through Edges that can be used to describe complex systems composed of a set of parts (corresponding to nodes) and their connections (corresponding to edges).
• Examples of graphs are road networks (junctions connected via roads), electronic circuit networks (components and their connections) and others
• Networkx is an excellent Python module for manipulating such Graph objects of any kind.
• Neo4j is a graph database. It uses the Graph as a data model to store such objects to a data store.

"""A very simple example to show what is required to get the excellent deform module from the Pylon's project to work with Flask.
DeForm is a Pylon's module capable of automatically creating HTML forms that conform to a schema of classes defined in Python through the Colander module. The transformation between Schema<-->Form data is handled by another module called Peppercorn. More information about how these three modules work together can be found at: http://docs.pylonsproject.org/projects/deform/en/latest/?awesome

Although DeForm is a Pylon's project, it can also operate as a stand-alone module. This Gist contains all the necessary changes to objects provided by Flask so that DeForm can serialize and deserialize data posted through a Flask.Request.

The basic thing that this gist is trying to demonstrate is how to derive from a Flask.Request object in order to change the data type of the Flask.Request.form object that stores the data posted by the client to the server. By default, Flask uses a MultiDict i
