Detailed Description

Rectangle class. Each instance of this class represents a rectangle whose sides are parallel to the axis. Such a rectangle represents all the points whose coordinates lies between well defined minimal and maximal values. Member functions can combine several rectangles by computing the intersection of rectangles ({intersect}) or the smallest rectangle enclosing two rectangles ({recthull}).
