// SampleModuleB.h
//
// This is part of the principal sample of how to use the ErrorLogger
// mechanism in a realistic setting.
//
// The overall structure assumed is that some programmer(s) provide a
// "framework" including the main program, various setups and event-flow
// controls, and so forth.  Then each group of physicists provide "modules"
// (or, in D0 language, "packages") which do steps of physics calculation --
// the framework will pass an event from package to package.
//
// This sample is composed of five files:
//	SampleFramework
//	SampleModule
// 	SampleEvent
//	SampleModuleA
//	SampleModuleB	contains the physics code written by group A to act
//			as module B.  This has just one .h and one .cc file,
//			though actual physics code would probably have
//			files for each indiviedual subroutine.
