Reverse SymPy LaTeX printer #11

SymPy has a LaTeX printer, the function latex( ) returns the LaTeX representation of the string.

It would be good to add tests, to check that latex2sympy is able to parse back generated LaTeX strings to SymPy's original expression.

Given a SymPy expression, let's say expr, test could look like:

from sympy import latex
assert eval(process_latex(latex(expr))) == expr

This could be used to both:

detect bugs in SymPy's LaTeX printer.
detect bugs in latex2sympy
