\addtogroup SELF_SupportRoutines @{ \fn AlmostEqual Compares two floating point numbers and determines if they are equal (to machine precision).

Base method for calculating entropy of a model When this method is not overridden, the entropy is simply set to 0.0. When you develop a model built on top of this abstract class or one of its children, it is recommended that you define a convex mathematical entropy function that is used as a measure of the model stability.

\addtogroup SELF_SupportRoutines @{ \fn CompareArray Compares to INTEGER arrays and determines if they are identical.

The entropy function is the sum of kinetic and internal energy For the linear model, this is
