def buildbounds(self, verbose = True):
		"""
		Build bounds for bok.
		By default I will make those bounds as wide as possible, still respecting epsilon.
		The parameter epsilon is the minimum distance two knots can have.
		If you give me a window size, I will not make the bounds as wide as possible, but only put them
		0.5*window days around the current knots (still respecting all this epsilon stuff of course).
