 *
 *      Functions used to implement routing.
 *
 *      To create a new routing message call:
 *         DialogBoxParam(hInst, "RouteNote", hWnd, RouteNoteDlgProc, (LPARAM) NULL );
 *      To route a routed message to the next recipient call:
 *          DialogBoxParam(hInst, "RouteNote", hWnd, RouteNoteDlgProc, (LPARAM) pmsg );
 *              where pmsg is a pointer to the message you want to route.
 *      To find out if a message was routed by this program call:
 *          HasRougingSlip();
 *
 *
 *      To use this functions in your own program change the line (in route.h):
 *          #define lpszSmplRTMsgClass "IPM.Note.SampleRoutingForm"
 *      to reflect the name of your own class for routing messages.
