special case to simplify setting up reactions of the form nA + mB = pC.
A subclass of RSreac for reactions of the form nA + mB = pC. These reactions can equivalently be implemented as A + A + B + ... etc, using RSLinkPlus and RSLinkIdent objects with a simpleRSreac, but the plusRsreac provides a convenient shortcut. The k-f and k-r fields are the forward and reverse rate constants. In addition there are three integer fields, nreac1, nreac2, and nprod for the quantities n,m, and p in the above equation.
See the interface for the ReactionScheme class to see how these reactions appear in practice.
