Added nosqlapi

[MatteoGuadrini]

What is this Python project?

This library is defined to encourage similarity between Python modules used to access NOSQL databases. In this way, I hope for consistency that leads to more easily understood modules, code that generally gets more portability across databases and a broader scope of database connectivity from Python.

What's the difference between this Python project and similar ones?

• Interface classes for all type of NOSQL database: key-value, column, documents and graph database.
• ODM classes
• Supports all CRUD operations
• Functions that facilitate connection and session management
