* arc.scad
*
* Create an arc. You can pass a 2 element vector to define the central angle.
* It provides a fn parameter consistent with the $fn parameter of the circle module.
* Its $fa, $fs and $fn parameters are consistent with the circle module.
* It depends on the circular_sector module so you have to include circular_sector.scad.
