Like lipsum, but for equations.

I wanted to create a lipsum-style generator for well formed equations, so I used L-Systems to create a little string replacement system. I'm pretty happy with how it turned out, but I have a couple of ideas for how I'd like it to develop. Here are a couple of those ideas:

• Redesign it to look like a LaTeX article, like in ./prototype
• Improve the replacement engine so it boosts the likelihood of replacements such as addition and division and reduces the likelihood of logarithms and exponentiations; the randomness isn't so pretty right now
• Allow for user input in some way (probably depth)
• Send equations through a CAS system to reduce them
