from	* a practical guide to splines * by c. de boor
to be called in
	c o l l o c .
constructs from the given breakpoint sequence
	b r e a k the knot
sequence
	t so that
spline(k+m,t) = pp(k+m,break) with
	m-1 continuous derivatives . this means that
t(1),...,t(n+kpm)
	= break(1) kpm times, then break(2),..., break(l) each   k times, then, finally, break(l+1) kpm times.

******	i n p u t ****** break(1),...,break(l+1)   breakpoint sequence l number of intervals or pieces kpm = k + m, order of the pp function or spline
******	o u t p u t ****** t(1),...,t(n+kpm)   the knot sequence. n = l*k + m = dimension of spline(k+m,t).
