Removed test comments. Changed variable name common_denom to denominator in CPattern and CCoef.
Added staticmethod to SymcaToolBox that converts a sympy expression to LaTeX string
Many changes made today. Mainly to the structure of SymcaToolBox where all methods are now static. Changed how maxima_factor works (checking for type of expression rather than using try..except). New class LatexOut.py to create a pdf with all the information contained in a Symca object. Should have made more incremental commits...
Refactored some code with more general usefulness into PyscesToolBox (also to prevent circular imports)
Fixed+refined previous commit
added .gitignore
Merge branch 'latex-out' into development
Latex out feature done
