Detailed Description

The core class for an equation of state.

This class holds the absolute minimum information to evaluate the equation of state. This includes the reducing state, limits on the equation of state, the coefficients for the Helmholtz derivative terms.

It does NOT include derived parameters like specific heat, enthalpy, etc.
