0010  Description: CPP macro used to register a new EventSetupRecord into the system
0011
0012  Usage:
0013     Special code is needed to 'register' a new class that inherits from EventSetupRecord with they system.  The
0014 macro EVENTSETUP_RECORD_REG is used to create that code.
0015
0016      Example: You have a new record defined called 'DummyRecord'.  Then to register that record with the system
0017      you place the line
0018
0019      EVENTSETUP_RECORD_REG(DummyRecord);
0020
0021      at 'file scope' (i.e., not within a namespace, class or function) in the .cc file for DummyRecord
