 * JTip is built on top of the very light weight jquery library.
 * Jack 2009-04-09 change log 
 * 1.In order to make jquery and prototype work together,use $jqry instead of $
 * 2.Fix the position for ie
 * 3.Use a.target to store the url which using to get hint text
 * Jack 2009-05-11 
 * 4.Fix the width of tool tip dialog if it's not enough area neither left nor right.
 * James 2010-09-03
 * 5.Added option to have delayed timeout (so tip will linger for a short time after mouseout) to support hyperlinks in tip
