// assertN.h 
//
// Graded assert macros
//
// There is no code gaurd in this file, since assert.h files can be 
// included multiple times.
//
// Usage:
//	assert1 (condition) will behave like assert(condition) but is 
//			    disabled by either NDEBUG or NDEBUG1.
//	assert2 (condition) is disabled by those and by NDEBUG2.
//	assert3 (condition) is disabled by those and by NDEBUG2 or NDEBUG3.
//
//	sanityCheck(condition) will behave much like assert(condition) but
//			       is disabled by NOSANCHECK rather than NDEBUG.
