// <synopsis>
// This class is a letter class for the envelope class
// <linkto class=LELCoordinates>LELCoordinates</linkto>.
// It acts as the coordinates class for Lattice objects without
// coordinates (like PagedArray).
//
// It does not do anything, but makes it possible that other classes
// (like <linkto class=LELImageCoord>LELImageCoord</linkto>)
// implement their own behaviour.
// </synopsis>
// <motivation>
// It must be possible to handle image coordinates in a lattice
// expression.
