Literally an implementation of the shunting-yard algorithm written at 6 AM.

I was curious about parsing M A T H and found out about this algorithm. Pretty cool and interesting.

This also includes a reverse Polish notation evaluator, since shunting yard produces an RPN expression.

RPN is easy for computers to interpret since it does not have an order of operations, but is just evaluated left to right.

main.py shows how you can use these to evaluate expressions writted in algebraic notation using the built in "calculate" function, which is itself in the same file.
