// Module: hulling()
// Usage:
// hulling(a, [keep]) ...
// Description:
// Takes the union of all children with tags that are in `a`, and hull()s them.
// If `keep` is given, then the result is unioned with all the children with
// tags in `keep`. If `keep` is not given, all children without tags in `a` are
// unioned with the result.
// Arguments:
// a = String containing space delimited set of tag names of children.
// keep = String containing space delimited set of tag names of children to keep whole.
// Example:
// hulling("body", keep="axle")
// sphere(d=100, $tags="body") {
// attach(CENTER) cube([40,100,100], anchor=CENTER, $tags="body");
// attach(CENTER) xcyl(d=40, h=100, $tags="axle");
// }
