/*
 * Add Link Titles and Icons
 *
 * This function will loop through all the elements in a page and add
 * a title attribute to all anchor tags.  For anchor tags with a className
 * of "external" the title will be "New Window:" followed by the link text.
 * For all anchor tags just the link text will be used for the title.  
 *
 * To override this functionality, just specify a title in the anchor tag.  
 * Anchors with defined titles will be ignored.
 * 
 * The function will also add icons for three classes of links:
 * internal, pdf, and doc.  Icons are added by writing the image tags
 * when the page loads. 
 * 
 *
