## Terminology
For purposes of these library files, the following terms apply:
- **Left**: Towards X-
- **Right**: Towards X+
- **Front**/**Forward**: Towards Y-
- **Back**/**Behind**: Towards Y+
- **Bottom**/**Down**/**Below**: Towards Z-
- **Top**/**Up**/**Above**: Towards Z+

- **Axis-Positive**: Towards the negative end of the axis the object is oriented on.  IE: X-, Y-, or Z-.
- **Axis-Negative**: Towards the negative end of the axis the object is oriented on.  IE: X-, Y-, or Z-.

## Common Arguments:

Args     | What it is
-------- | ----------------------------------------
rounding | Radius of rounding for interior or exterior edges.
chamfer  | Size of chamfers/bevels for interior or exterior edges.
orient   | Axis a part should be oriented along.  Given as an XYZ triplet of rotation angles.  It is recommended that you use the `ORIENT_` constants from `constants.scad`.  Default is usually `ORIENT_Z` for vertical orientation.
anchor   | Side of the part that is aligned with the origin.  Given as a vector away from the origin.  It is recommended that you use the directional constants from `constants.scad`.  Default is usually `CENTER`.
