some dirty code to look into

[AlekseyCherepanov]

I've wrote some code using Symbolism. It is interesting enough to be
shared. It is not ready to be integrated and I don't have time to
finish it. So I publish the mess as is.

The code includes:

• MakeFunction() to create custom functions,
• Subs() to substitute (custom) functions using callback (and
  SubsFunctionStatic() to substitute variadic functions),
• my own tree traversal with replacement by callback (like
  DeepSelect() but goes bottom-to-top),
• Output to LaTeX, either to .tex file or to .html file that includes
  MathJax,
• parser based on compilation (just for fun, not for real use!),
• some examples of usage,
• minor stuff.
