More matlab like set functions, tens to hundreds of times faster than
the corresponding matlab functions:

	unique, union, intersect, setdiff, setxor, ismember

The equivalent octave functions are:

	create_set -> unique
	intersection -> intersect
	union -> union
	complement(y,x) -> setdiff(y,x)

These are not exact equivalents.  The matlab functions return either
row or column vectors depending on their inputs whereas the octave
functions always return row vectors.  Neither handle the matlab
'rows' option.
