Detailed Description

A class for generating concrete EvtTimeShiftI derived classes based on the factory pattern. This code supplies a CPP macro which allows the classes to self-register and thus no modification of this class is needed in order to expand the list of classes it knows about.

Implemented as a singleton holding a map between names and pointers-to-functions (that call a class default constructor). The functions pointers must return EvtTimeShiftI*.
