Cantera/Adding Python Class Via C++

The following instructions describe how to implement a new C++ class in Cantera 2.1 and make it accessible via Python.

Hopefully this will save you the headaches and streams of expletives that navigating changes between 2.0 and 2.1 caused me.

Overview

To add a new C++ class in Cantera, you will need to follow a couple of steps:

1. Add the C++ code for the class

2. Wrap the new C++ code with the C API

3. Create a Python object that calls the C API code

4. Create a Cython object

This fourth step is new to Cantera 2.1.
