// RADEventsXML::ConstructEventNode
//
// Creates an XMLEvent node from a RADEvent object
//
// An example XML node as text:
// <Event num="0057"
// starttime="0000020010826175602000" endtime="0000020010826175827000"

// sum="10941.0" maxvalue="84"
// starttimedisplay="2001.08.26 - 17:56:02"
// endtimedisplay="2001.08.26 - 17:58:27"
// maxtimedisplay="2001.08.26 - 17:57:02"
// etype="Channel"
// stationname="GRAND 2" />
//
// Note: the text attribute values are created from the strings
// on the RADEvent object.
//
// Input:
// pEvent - the RADEvent instance
//
// Returns:
// IXMLDOMElement: the constructed Event node,
// or a NULL pointer if processing failed.
