Reorganise documentation & usage example

- Move Quick Sample into its own usage.rst page of the doc,
  as it is only correctly rendered in a Sphinx documentation.
- Move Changelog inclusion into its own page of the doc,
  as its growing size took a lot of space in the hom page.

These two changes leave a lot more room for the table of
contents, as it was quite burried in the home page before.

Fixes #41
