//
//Notes:
//  The element should look something like:
//  <span class='custom-radiobutton' css-unchecked="radiobutton-unchecked" css-checked="radiobutton-checked" value="false"> My text goes here!</span>
//  The unchecked and checked css should at a minimum specify a height & width and a background image set to no-repeat.
//
//  Depends on several CSS classes:
//  .non-selectable-text {-webkit-user-select: none; -khtml-user-select: none; -moz-user-select: none; -o-user-select: none; user-select: none;}
//  .clickable {cursor: pointer; cursor: hand;}
//
