 * ie6Layout.js
 * Adapts IE to behave according to standards

 *
 * Argh! IE6 exhibits a miserable sort of behavior when you have a page
 * laid out exclusively with floats.
 *
 * This function pulls all labels with CSS "clear" set, and adds a meaningless
 * in-flow DIV before them to force IE to flow properly, without compromising
 * our standards-compliant code.
 *
 * Currently, IE7 runs Sundial in "old quirks" mode, so it exhibits the same
 * behavior. If we later update our DOCTYPE, this can change.
