Initial rough outline with basic CLI.
Minimal metadata required for Python packaging.

Renamed .md file to .txt and made a soft link from README.rst
to the .txt file. This allows both Python packaging tools to do
the correct thing as well as providing a nicely rendered README
on github.
Changed to separate client/server and added future.
Finished basic client + server.

Server is based on the idea of simulating variants rather than reading
them from a VCF file, saving some tedium and also allowing for us
to serve data from an arbitrarily large data set without running into
scalability issues.
