	I think we need to find a between input shortcuts and 
	feasiblity. One could just use unicode 02016 and \Vert.
	In unicodemath you also have \Vvert for three bars.

	The proper way to lay this out is with a little whitspace between
	the to values, so input should be |z| |w| and not as |z||w| !

	See above!
