class EdgeEnd extends Comparable[EdgeEnd]

Models the end of an edge incident on a node. EdgeEnds have a direction determined by the direction of the ray from the initial point to the next point. EdgeEnds are comparable under the ordering "a has a greater angle with the x-axis than b". This ordering is used to sort EdgeEnds around a node.

    Implements the total order relation:

    a has a greater angle with the positive x-axis than b

    Using the obvious algorithm of simply computing the angle is not robust, since the angle calculation is obviously susceptible to roundoff. A robust algorithm is: - first compare the quadrant. If the quadrants are different, it it trivial to determine which vector is "greater". - if the vectors lie in the same quadrant, the computeOrientation function can be used to decide the relative orientation of the vectors.
