Detailed Description

Namespace PIDDef holds all constants necessary for Particle ID.

In particular, we define particles that we can assign ID's to and detectors that are capable of doing particle ID. This info is to be stored in RBPID class and classes that inherit from it. Notice that detector enum also exists in DetDef namespace. Here the namespace is extended by some useful functions that are implemented in the .cxx and require linking against this lib.
