// Function       : A list of buttons which can be enabled or disabled 
//                  together. Intended for use with list box, each button
//                  can be set to become enabled only if a single item is 
//                  selected, only if multiple items are select, if any number
//                  of items are selected, or if there are more than a certain
//                  number of items (selected or not) in the list box.
