OpenSCAD Fillet Angle Module/Library

This module accepts 3 points and a radius value and draws an arc of the supplied radius at the middle point as a polygon. Since it can't know what side of the angle should be filled, it assumes you're supplying the points in a clockwise manner.

There is a 5th parameter for the number of segments to use when drawing the arc.

This module uses my 2dWedge module [here](http://www.thingiverse.com/thing:1843282) as a dependency - make sure you download all the files on this page.
