// Description: creates a wand that detects CAVE wand button events
//
//<b>notes:</b>
//<ul>
//<li> derived nodes inherit all messages from their base classes
//<li> see reset method for default settings
//<li> this node can also be created with the alias: CAVEWand
//<li> this node should be a child of a <a href="ygCAVETracker.html">ygCAVETracker</a> node
//<li> this node is required for <a href="wandTrigger.html">wandTrigger</a> node detection
//<li> when pressed this node generates buttonX events where X is the button number
//<li> when released this node generates buttonUpX events where X is the button number
//</ul>
