    point.angleBetween(p1, p2)

Compute the angle (in degrees) between the line from this point to `p1` and the line from this point to `p2`.

The ordering of points `p1` and `p2` is important. The function returns a value between 0 and 180 when the angle (in the direction from `p1` to `p2`) is clockwise, and a value between 180 and 360 when the angle is counterclockwise. The function returns `NaN` if either of the points `p1` and `p2` is coincident with this point.
