analytic Heston-model engine based on Fourier transform
Integration detail: Two algebraically equivalent formulations of the complex logarithm of the Heston model exist. Gatherals  (also Duffie, Pan and Singleton , and Schoutens, Simons and Tistaert) version does not cause discoutinuities whereas the original version (e.g. Heston ) needs some sort of 'branch correction' to work properly. Gatheral's version does also work with adaptive integration routines and should be preferred over the original Heston version.
