Lumped thermal element with variable heat capacity

Information

Similar to the HeatCapacitor block in the MSL, except that the specific heat capacity is allowed to vary according to the temperature: c_v(T)=c_p(T) (good approximation for solids). The heat capacity is the sum of those determined via the Debye model (lattice phonons) and the Fermi-Dirac distribution (conduction electrons). This approach is fitting for many solids, both electrically-conducting (Ne>0) and electrically-insulating (Ne=0).

Numerical outputs include the Debye-model energy density, the total specific heat capacity, and the Fermi-Dirac energy density above the zero-point (T=0) energy density.
