Create Bitbucket wiki

A Bitbucket wiki can be useful to quickly introduce the software.

For starters, thie could be a simple "Hello, world" application to illustrate the use, but we should be able to extend with files from the Sphinx-documentation.

I think it's sufficient to link to the full documentation, and the demos there.
