pykpp is a KPP-like chemical mechanism parser that produces a box model solvable by SciPy's odeint solver

1. Open DOS Prompt on Windows or Terminal on Linux/Mac OSX
2. Type "python -m pykpp model.kpp" where model.kpp is a valid KPP input file.
3. Example below assumes Installation and that cbm4.eqn has been downloaded to the downloads folder

C:\Users\MyUserName\Downloads>python -m pykpp cbm4.eqn
