// 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();
