/** This a available->selected widget.
  * This is a fairly complex widget set.  It is used for when you have a list of 
  * available options in one list box and a list of selected items in a second box 
  * and arrows to add/remove them from one to the other.
  *
  * This widget assumes that the left side is the available ones and the right side
  * is the selected ones.
  *
  * Widget is defined as:
