/*
* Added by MRH on 27-Aug-2009 This hard-coding is necessary for rxn family templates that are labeled
* "thermo_consistence". After the chemgraphs are mutated, the central nodes for the products are not correct
* (see example below). These hard-coded portions are necessary for RMG to find Kinetics for the structure.
* Example: CH4 + H CH4 1 *1 C 0 {2,S} {3,S} {4,S} {5,S} 2 *2 H 0 {1,S} 3 H 0 {1,S} 4 H 0 {1,S} 5 H 0 {1,S} H 1
* *3 H 1 After RMG has "reactChemGraph" and "mutate" the chemgraphs of the reactants, the products would look
* as such: prod1 1 *1 C 1 {2,S} {3,S} {4,S} 2 H 0 {1,S} 3 H 0 {1,S} 4 H 0 {1,S} prod2 1 *3 H 0 {2,S} 2 *2 H 0
* {1,S} Assuming the reaction as written (CH4+H=CH3+H2) is endothermic at 298K, RMG will label this structure
* as direction=-1 (backward). When attempting to find Kinetics for the backward reaction, RMG will try to match
* the prod1 graph against the generic graphs X_H and Y_rad_birad. It cannot match Y_rad_birad (because there is
* no *3 node) and it cannot match X_H (because there is no *2 node). Thus, a "null" Kinetics will be returned
* from the findReverseRateConstant call. We then relabel the central nodes on prod1 and prod2 and attempt to
* get Kinetics for this structure. I am adding the following bit of code to work with the new reaction family
* Aaron Vandeputte is adding to RMG: "".
