Adds Jupyter notebooks and MATLAB live scripts to the examples

[alexhroom]

This PR fixes #18 by splitting the examples folder into a separate folder for each language. The MATLAB folder contains the tutorials, with HTML exports of the live scripts embedded. The Python folder contains Jupyter notebooks converted via nbsphinx.

Thanks for this, see comments

1. Please update README with instruction to build example and install Pandoc
2. The instruction to run the Python examples have been removed and I think that information is arguably more important than adding the notebooks so we have to add them back. We could consider moving the Examples up one level out of the user guide so the navigation will look like
   Home Installation User Guide Examples References
   This should give more flexibility so we can have instructions to run the examples and notebooks separately.
3. I don't know what's going on here with the duplicate numbers

there is a setting for nbconvert where you can add a prolog to notebooks, with information on how to run them (see e.g. the nbconvert docs, entirely written in Jupyter, where they use the prolog to provide download and binder links). Would adding the information on how to run the scripts to the prolog do?

I don't know how it will look but we also need instructions for people running the examples as a script or function not just the notebook. People might ignore the prolog and assume its for the notebook users

@StephenNneji the prolog doesn't have to resemble the one in the example I gave: it just lets you put a block of text before the notebook. This would have the same structure as the MATLAB examples

Looks good, please see comments
