//-----------------------------------------------------------------------------
// Usage model for the Dbg library
//
// 1. Assertions.
// 
//   Assertions are used to detect and warn about invalid states
//   
//   To use an assertion, use
//
//   Assert( (f == 5) );
//   AssertMsg( (f == 5), ("F needs to be %d here!\n", 5) );
//   AssertFunc( (f == 5), BadFunc() );
//   AssertEquals( f, 5 );
//   AssertFloatEquals( f, 5.0f, 1e-3 );
//
//   The first will simply report that an assertion failed on a particular
//   code file and line. The second version will display a print-f formatted message 
//   along with the file and line, the third will display a generic message and
//   will also cause the function BadFunc to be executed, and the last two
//   will report an error if f is not equal to 5 (the last one asserts within
//   a particular tolerance).
//
// 2. Code activation
//
//   To cause code to be run only in debug builds, use DBG_CODE:
//   An example is below.
//
//   DBG_CODE(
//				{
//					int x = 5;
//					++x;
//				}
//           ); 
//
//   Code can be activated based on the dynamic spew groups also. Use
//  
//   DBG_DCODE( "group", level,
//              { int x = 5; ++x; }
//            );
//
// 3. Breaking into the debugger.
//
//   To cause an unconditional break into the debugger in debug builds only, use DBG_BREAK
//
//   DBG_BREAK();
//
//	 You can force a break in any build (release or debug) using
//
//	 DebuggerBreak();
