This is a rust port of the Chemical Equilibrium with Applications method. 
Code was generally developed following the approach described in and not really from referencing the [NASA open source codebase](https://github.com/nasa/cea).

## Completeness

Below are the list of solvers in CEA and whether they are currently supported or not:

- [ ] TP, HP, SP
- [ ] TV, UV, SV
- [ ] CJ detonation
- [ ] shock
- [ ] rocket
