Move MATLAB codegen to Jinja2

[korken89]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Lets move the matlab codegen to Jinja2 templates, the current template code is very hard to read and see how it comes together.
This will also help with the C/C++ lib generation and overview IMO.

Describe alternatives you've considered
Keep it as it is.

Jinja is not supported in MATLAB, but there's Lobster (but it looks abandoned).

Matlab can call into python, that should be enough

@korken89 that's certainly a legit solution. I'm just concerned that users will need to install the Python package - not too difficult, but the less one does during installation, the better it is.

Hey guys, you could write your functionality in Java and invoke it from Matlab, since Matlab is natively Java I believe.
This would require your jar in Matlab's classpath though, not sure if you could do this through an add-on.
Cool project btw!

MATLAB codegen has become legacy code. We'll be releasing a new MATLAB API in #408 in the next few days. We'll need to redesign the MATLAB codegen at some point.
