ARC2 angle radius

Moves the turtle along an arc (part of a circle). The arc sweeps an amount given by the angle input. The size (curvature) of the arc is based on the radius input.

If angle is positive, then the turtle moves forward in a clockwise direction. If angle is negative, then the turtle moves backward in a counter-clockwise direction.
