 *      This function is designed to force the HTML document to extend the entire 
 *      height of the browser window by forcing the min-height attribute on the 
 *      html element that is responsible for holding content on the page.
 * 
 * var emh = Existing Minimum Height as specified in the primary CSS document.
 *            There is no need to extend the min-height attribute in cases where 
 *            the min height is already greater than the window height.
 * var nsh = Non-Scaling Height is the combined height of elements not to be 
 *           included in the calculation of the new min height
