Option Pricing PROJ Method (Exotic/Vanilla Options)

Option pricing (exotic/vanilla derivatives) based on an efficient and general Fourier transform pricing framework - the PROJ method (short for Frame Projection). The modules are organized by Pricing Method, then by Model, and then by Contract Type. Each contract has a run script, which starts with "Script_", e.g. "Script_BarrierOptions.m". Monte Carlo and other pricing libraries are also provided to support R&D.
