    point.angleBetween(p1, p2)

Computes the angle (in degrees) between the line passing through the point and point `p1` and the line passing through the point and point `p2`. The ordering of points `p1` and `p2` is important. The function returns a value between 0 and 180 degrees when the angle is counterclockwise, and a value between 180 and 360 degrees when the angle is clockwise. The function returns NaN if any of the points `p1` and `p2` are coincident with this point.
