Provide the example's source code in the documentation

[luisfabib]

Currently, there are examples provided in the documentation (e.g. see here), but the corresponding pages point out a file in one of the provided distributions (demo_MMMx.zip) and then proceed to discuss that example.

The source code of the example's file (.mcx) should be provided in the documentation. Sphinx easily allows to include a source code file as a literal code block:

.. literalinclude :: <path/to/file>
   :language: <file_language>

This will include the full example source code in the example's documentation without the need of any code duplication and zero maintenance effort.

This would also allow the inclusion of the examples with the source code and the executable users to just get them from the documentation.
