Title: Load Dependent Station Service Strategy

Description: This object holds informations for a load dependent service strategy. The strategy is organized in subsequent ranges (starting from 1 to infinity), and each of them can specify a distribution, its c (if any, fixed) and its mean value as a function of load into the station.
