Support for \newcommand substitution

[fleimgruber]

Kudos to you for this project, thanks!

I played around with it to get a basic example working, but when I want to use it with existing LaTeX then I often have the case that the LaTeX contains commands that have been defined in the preamble or a .sty file with \newcommand{\alias}{\somemath}. This could be solved in the calling code such that latex2mathml only sees the substituted strings, but the substitution then has to happen manually, e.g. via a Python dict that represents a math_commands.sty with the command mappings and ad-hoc string (regexp?) substitution code.

Any idea how this might be supported within latex2mathml? Or do you consider this out-of-scope?
