min and max from <algobase.h>

	template <class T>	inline const T& (min) (const T& a, const T& b)	{...}
		
	template <class T>	inline const T& (max) (const T& a, const T& b)	{...}

	min and max only work on the items passed to them.
	The don't need iterators (or contains).

	min_element() and max_element() work on a group of
	items so they iterators (which presumably refer to
	items in a container).

	template <class itr>	itr min_element (itr first, itr last)	{...}

	template <class itr>	itr max_element (itr first, itr last)	{...}
