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.
