/*
ReactionSystem.h
ReactionSystem is the base class from which all kinematics calculations should inherit. It contains all members and functions
to perform a single step reaction/decay, which is the basic building block of all subsequent types of reactions in MASK. More
complicated systems (see TwoStepSystem and ThreeStepSystem) add further data members and override the virtual functions.
