The base letter class for lattice coordinates in LEL.
Internal
This class is a letter class for the envelope class LELCoordinates . 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 LELImageCoord ) implement their own behaviour.
It must be possible to handle image coordinates in a lattice expression.
