 // Arguments:
+//   spacing = spacing of copies per axis. Use with `n`.
+//   n = Optional number of copies to have per axis.
 //   xa = array or range of X-axis values to offset by. (Default: [0])
 //   ya = array or range of Y-axis values to offset by. (Default: [0])

 //
 // Side Effects:
 //   `$pos` is set to the relative centerpoint of each child copy, and can be used to modify each child individually.
 //   `$idx` is set to the [Xidx,Yidx,Zidx] index values of each child copy, when using `count` and `n`.
