// NOTE 1: The radiobutton-based forms are handled a bit oddly. The handling
// of these forms is based on the assumption that the radiobuttons are not
// displayed. All click events are handled through the radiobutton's label.
//
// Classes are assigned to the labels based on their state-- clickable,
// not clickable, or already-clicked. The CSS associated with these classes
// change the appearance of these labels based on which classes are assigned.
// Therefore, the Javascript herein concerns itself with changing the classes
// assigned to labels, and leaves the display to CSS.
//
// The "select"-based dropdown boxes are not handled in any unorthodox manner.
// They're pretty straightforward.
///////////////////////////////////////////////////////////////////////////////

///////////////////////////////////////////////////////////////////////////////
// NOTE 2: Thanks to the brain-dead nature of Internet Explorer CSS selectors,
// all classes must be aggragated into a single class.
//
// An element in Internet Explorer can have multiple classes, but you can't build
// CSS selectors with multiple classes. For instance, assume an element E1 with
// class="green blue red", and an element E2 with class="red". The CSS selector
// S1 ".green .red" will select *BOTH* E1 and E2 in Internet Explorer. This is
// a fairly disasterous bug, in that it screws up our combinational logic.
//
// To get around that, aggregate the classes into a single "super-class."
// This super-class is built from the other assigned classes. So, there are three
// types of classes:
//
//    Direction: "karma_up" | "karma_down"
//    Clicked:   "karma_clicked"
//    Clickable: "karma_clickable" | "karma_not_clickable"
//
// Three distinct bits = eight possible combinations:
//
//       karma_up_clicked_clickable
//       karma_up_not_clicked_clickable
//       karma_up_clicked_not_clickable
//       karma_up_not_clicked_not_clickable
//       karma_down_clicked_clickable
//       karma_down_not_clicked_clickable
//       karma_down_clicked_not_clickable
//       karma_down_not_clicked_not_clickable
