Add Makefile for tests, build, clean, docs
Add Makefile for tests, build, clean, docs

Simplifies some common jobs, like creating the docs from the root
directory.
The clean target could actually remove more things, like for example
doing "clean" on the docs as well.

The release target is not very usefull as it is, as it just opens the
__init__ file in vim.
