Class implementing streams for use in mixing and or reaction problems. This is writting in terms of mixture fraction with streams defined in an input file. The class can implement products of complete combustion, or equilibrium (through the Cantera IdealGasPhase object, if desired). This class holds a pointer to a Cantera IdealGasPhase object (defined up front in main) that computes thermodynamic, kinetic, and transport data.
