FastCaloSim shower shape tuning to data
This MR adds a class for the FastCaloSim lateral shower shape tuning to data. It implements the 2D eta_s - phi_s scaling model for the layer 2 tuning as well as the cubic series model for the layer 1 tuning of shower shape variables as described in the PUB note. It also implements the loading of the respective model parameters.
