// Implementation version v0 of PHOS Manager class 
// Layout EMC + PPSD has name GPS2  
// The main goal of this version of AliPHOS is to calculte the 
//  induced charged in the PIN diode, taking into account light
//  tracking in the PbWO4 crystal, induced signal in the 
//  PIN due to MIPS particle and electronic noise.
// This is done in the StepManager 
//
