Creates a pie (circular sector). You can pass a 2 element vector to define the central angle. Its `$fa`

, `$fs`

and `$fn`

parameters are consistent with the `circle`

module.

## Parameters

`radius`

: The radius of the circle.`angle`

: A single value or a 2 element vector which defines the central angle. The first element of the vector is the beginning angle in degrees, and the second element is the ending angle.`$fa`

,`$fs`

,`$fn`

: Check the circle module for more details.

## Examples

```
include <pie.scad>;
pie(radius = 20, angle = [210, 310]);
translate([-15, 0, 0]) pie(radius = 20, angle = [45, 135]);
translate([15, 0, 0]) pie(radius = 20, angle = [45, 135], $fn = 12);
```
