 * runOnLoad.js: portable registration for onload event handlers.
 *
 * This module defines a single runOnLoad( ) function for portably registering
 * functions that can be safely invoked only when the document is fully loaded
 * and the DOM is available.
 *
 * Functions registered with runOnLoad( ) will not be passed any arguments when
 * invoked. They will not be invoked as a method of any meaningful object, and
 * the this keyword should not be used. Functions registered with runOnLoad( )
 * will be invoked in the order in which they were registered. There is no
 * way to deregister a function once it has been passed to runOnLoad( ).
 *
 * In old browsers that do not support addEventListener( ) or attachEvent( ),
 * this function relies on the DOM Level 0 window.onload property and will not
 * work correctly when used in documents that set the onload attribute
 * of their <body> or <frameset> tags.
