"""
I'm starting to like the Variance-Gamma model quite a bit.
Here is a quick and dirty Octave (Matlab) code for generating the IV skew given VG parameters
I took the parameters from the Madan, Carr and Chang paper.
Instead of evaluating a double integral I use the mixing formula, which results in a single integral.
