Wikipedia tells that the Voigt profile & functions are related to the 
complex error function w(z) = exp(-z^2)(1 - erf(-i z)). Scipy has an 
implementation for erf() that supports complex values.

However, be sure to use Scipy >= 0.8.0, as the erf() implementation in 
earlier versions had bugs that made results from erf() inaccurate in 
parts of the complex plane.
