lib.thermo module

Module with common thermodynamic utilities:

• Thermo: Class with common functionality for special thermo model

• ThermoWater: Thermo subclass with water specific properties, for iapws and freesteam

• ThermoAdvanced: Thermo subclass with additional properties for advanced model like coolprop, meos

• ThermoRefProp: Thermo subclass with specific properties availables in refprop
