mostly done with the Module part of the basic tutorial - added support for :math: directive (requires Sphinx >= 0.5.1)

rewrote index page and added a link to oplist and typelist for use with :ref:, moved LICENSE, a picture and the glossary up one level

function_to_module: creates a dummy module, with the same input / output parameters as the function, and with the same behaviour

put a test as a knowfailure. This way it won't distract people to look at it now. We should maybe look into it after the scrum.
