, 18 Aug 2003
Introduction to the allocator concept, as well as implementing a policy-driven allocator template class

		//	Converts each integral constant into a unique type
		//	Useful for compile time if-else statements

//	helpers for << operators

		//	since unable to overload << due to ambigous calls,
		//	resort to create type traits, and overloading those with problems
