Compute complex error functions, based on a new implementation of Faddeeva's w_of_z. Also provide Dawson and Voigt functions.
Uses methods similar to the erfcx calculation: continued fractions for large |x|, a lookup table of Chebyshev polynomials for smaller |x|, and finally a Taylor expansion for |x|<0.01.
