Allow an element to have more than ONE parent

Ramesh Errabolu

Currently an element is defined to have only one Parent. Is it possible to edit an element and specify an additional parent. For example one can start a node with one parent and then go through its context menu (style bar) and add more parents iteratively. So to define a node with 4 parents one can create the element in the normal way and go through the style bar three times to identify the additional parents.

This will help draw relationships that are different than the Connections which one can attach to an element.
