 // The "ddcl" object that contains all the DDCL extension/support code.
 // DDCL: drop-down checkbox-list wrapper code to ui.dropdownchecklist.js jQuery widget.
 // The reason for extension/support code beyond the jquery widget is that
 // We have changed some widget functionality:
 // - Closed control show all currently selected options in multiple lines with CSS
 // - Open control can gray out invalid choices
 
 // NOTE:
 // Currently tied to ui.dropdownchecklist.js v1.3, with 2 "UCSC" changes:
 // - Chrome multi-select required changing ddcl code as per issue 176.
 // - IE needed special code to block window.resize event in DDCL.
 // *** v1.4 has been released which works with jquery 1.6.1 ***
 
 // Some useful names defined:
 // ddcl: This object just contains these supporting functions in one package.
 // multiSelect: original <SELECT multiple> that ddcl wraps around
 //  (AKA filterBy: all mutiSelects are of class .filterBy [may also be .filterComp, .filterTable])
 // selectOptions: original multiSelect.options (get updated, sent to cart, etc.)
 // control: The whole gaggle of elements that get created when one multiSelect becomes a ddcl
 // controlLabel: Just the text inside the closed control
 // controlSelector: the closed box waiting to be clicked
 // dropWrapper: The div that contains all the checkboxes and is only seen when the DDCL is open
 // allCheckboxes: one to one correspondence with selectOptions
