double	computeThValue ()
	Empty constructor.
double	F (const double m02, const double m12) const
	Function \(F(m02,m12)\) used for THDM. Remember that this function is defined for THDM while for SUSY we have a multiplicative factor 2.

	A get method to get the model.
const std::vector< std::string >	getParametersForObservable ()
	A get method to get the parameters for the specific observable.
