WIP. A command line app which takes as input an algebraic expression and simplifies it (e.g. "2*x-(-3)*4" to "2*x+12"). It optionally takes values for the variables in the expression, which it uses to simplify the expression further. If you input "2*x-(-3)*4" "x=2", then the output would be "16". Note that quotes around inputs is not required if they do not contain whitespace or the character ^.
