Detailed Description

An abstract base class for evaluating all reactions of a particular type.

Because this class has no template parameters, the Kinetics object can store all of these rate coefficient evaluators as a vector<shared_ptr<MultiRateBase>>. All of the actual implementation for this capability is done in the MultiRate class.
