Ga4gh-server

- Fixes dense variants not being correctly handled by the server (391)
- Removes unused paths (thus they won't confusingly show up in the HTML display at / )

This is a beta pre-release of the GA4GH reference implementation. It includes
- A fully functional client API;
- A set of client side tools for interacting with any conformant server;
- A partial implementation of the server API, providing supports for variants and reads from native file formats.

This is a alpha release to allow us test the PyPI package and documentation.

This is an early alpha release to allow us to test the PyPI package and the README. This is not intended for general use.
