// THaPhysicsModule
//
// Abstract base class for a "physics" processing module.
//
// Physics processing takes place after detector and apparatus
// processing, i.e. after basic tracking. Physics modules 
// combine data from different apparatuses.
//
// Examples:
//  - Vertex calculations (e.g. "reaction_z")
//  - Vertex corrections  (e.g. extended target corrections)
//  - Target energy loss calculations (requires beam position and tracks)
//  - single-arm and coincidence kinematics corrections.
//
// These routines typically require some "global" database information
// such as spectrometer angles, central momentum, target parameters, etc.
// Some database functions are provided.
