Added function for including reactions that are elementally balanced and fixed a couple of bugs
Adding options to ignore or include protons/water when balancing reactions
Correcting charge of proton
Adding/Fixing functions for detecting protons and water and rejecting elementally unbalanced reactions
Added exception for problematic formulas
Rewrote sections of checkReactionMassChargeBalance() function, returns better status, and can integrate proton/water balancing
