// Description:
// Spreads out each individual child along the direction `dir`.

// Usage:

// spacing = Spacing to add between each child. (Default: 10.0)

// l = Length to distribute copies along.
//
// 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 index number of each child being copied.

// distribute(sizes=[100, 30, 50], dir=UP) {

// cube([10,20,30], center=true);
