Functions
STD::complex< double >	evalCerf (double swt, double u, double c)
STD::complex< double >	evalCerfApprox (double _x, double u, double c)
	use the approximation: erf(z) = exp(-z*z)/(STD::sqrt(pi)*z) to explicitly cancel the divergent exp(y*y) behaviour of CWERF for z = x + i y with large negative y
