/**
*This function contains the code which allows items to be
*grouped (contain each other) and considered one item.
*Releasing an item you are dragging over another item (while
*holding shift) makes the first item the second items child.
*This means that the first item can nolonger be iteracted with
*and that moving or reordering the second item will cause the
*same to happen to the first item. Any number of items can be
*made children of an item but if you make an item with a child
*a child that items child will disapear.
*
*This satisfies the "move range of items" requirement, goal F
*and the "ojects can contain objects" requirement, goal I
