GraphEngine now can initialize with a much more robust set of reactions (including the entire reaction set). The jacobian can still be efficiently evaluated using CppAD's sparse jacobian feature. Further, the primeing network has been signifiganty enhanced to handle much hotter termperatures
Fized stoichiometry matrix initialization, added penames to reablib reactions, began work on LogicalReaction to sum the contributions of different fitting functions provided by reaclib
GraphNetwork is intended to be a more general, reaclib based, network when compared to approx8 (which is also approx8 based but limited to a specific composition)
This is a very basic wrapper implimentation currently. This is sufficient to lock the interface down so that other code can target it. However, internally there is just a "convert" function. Eventually we should rework the code itself to use the composition module more directly.
