/**
 * Takes an element id. This function does nothing if the element
 * does not exist or if the browser does not support JS:DOM. 
 * 
 * Notes:
 *    1. Use on block elements (inline elments will get converted to
 *       blocks if you call show on them)
 *    2. Hiding an element will recalculate document flow to account
 *       for the removal of the element from the rendering pipeline.
 *    3. This script replaces an older version which was using
 *       deprecated JS browser detects.
