CubicSpline: For Entropy and Enthalpy for the crystal form stable at T = 0 K derived from integration of Csat

The heat capacities are assumed to follow a simple T cubed form below the lowest measured temperature above T = 0 K. This form is assumed only if the lowest temperature is 20 K or lower. Otherwise, the derived thermodynamic functions are not calculated.

Information provided on the Equation Parameters form includes details of extrapolations to T = 0 K for the lowest temperature phase.
