title: ColumnViewerTooltipSupport in SWT
body: <p>What is the exact use of <code>ColumnViewerTooltipSupport</code>? I know that it provides tooltip support for <code>ColumnViewers</code> but does it mean that it provides tooltip for treeViewers? How can I use this feature to provide tooltip support individually different tooltips for my each tree item when the mouse hovers over each item? Do I require a <code>MouseListener</code> for this or does the <code>ColumnViewerTooltipSupport</code> class provide it by default? Can someone please help me out here as I'm relatively new to SWT concepts.</p>
  
  <p>My tooltip has multiple lines, How can I wrap the text and display it neatly? It seems like <code>ColumnViewerToolTipSupport</code> class does not wrap the tooltip text if the text is too long. I would like to use a tooltip window with a vertical scroll bar just like the InformationControl Windows in eclipse? If something like eclipse is not possible then just a tooltip window with wrapped up text.</p>
  
  <p>Please show me an example snippet?</p>
