Summary: "inverse_erf" doesn't allow complex arguments

Initial Comment:
"erf" allows both real and complex arguments. It gives complex results when the arguments are complex. Its inverse, inverse_efc, however, only allows real argument.
E.g.
inverse_erf(0.5)  gives:  0.47693627620447
inverse_erf(0.5*%i) gives:  inverse_erf(0.5*%i)
