Compares two sets of objects, linking objects in "child" set to the nearest object in the "parent" set... pretty simple!
1. Select set to be children and run script or press refresh children.
2. Select set to be parents and press refresh parents
3. Press "Parent"
*4. You can also press "select objs w/o children" to select any objects left in the parent list with no children (can happen if it's far enough away that it's not the closest to any object in the child set.)
