// This derived LEL letter class handles access to the pixels in a Lattice
// </etymology>
//
// <synopsis>
// This LEL letter class is derived from LELInterface. It
// is used to construct LEL objects that access the pixels in
// a Lattice. It works with Lattices of type
// Float,Double,Complex,DComplex and Bool.
//
// A description of the implementation details of the LEL classes can
// be found in
// <a href="../notes/216.html">Note 216</a>
// </synopsis>
//
// <example>
// Examples are not very useful as the user would never use
// these classes directly. Look in LatticeExprNode.cc to see
// how it invokes these classes. An example of how the user
// would indirectly use this class (through the envelope) is:
// <srcblock>
// IPosition shape(2,5,10);
// ArrayLattice<Float> x(shape); x.set(1.0);
// ArrayLattice<Float> y(shape);
// y.copyData(x); // y = x
// </srcblock>
// </example>
//
// <motivation>
// Accessing Lattices is fundamental to manipulating their pixel values
// </motivation>
//
