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
