Coulomb correction parametrization based on a Levy source

Description

This package contains a calculation for quantum-statistical correlation functions, including Coulomb-correction, interpolated from numerical integration calculations, detailed in the below mentioned calculations. Range of validity is R=2-12 fm for the HBT (Lévy) scale and alpha=0.8-2.0 for the Lévy exponent. The lambda parameter is included only in the correlation function calculations, as done in a Bowler-Sinyukov type of treatment.
