// the following wrapper function of window.open() allows a user to specify
//
// o url  : the destination URL,
// o wname: the window's name (e.g. for target) 
// o w    : window width, 
// o h    : window hight, 
// o loff : offset from left edge of the display, 
// o toff : offset from the top edge of the display, and 
// o aoff : auto close the window (optional)
// o ctime: a given wait time before window closure (optional)
//
// if aoff is not given, then ctime shouldn't be given either.
