33--  Performs a case-insensitive equality test of Left and Right. This is
34--  useful as the generic actual equivalence operation (Equivalent_Keys)
35--  when instantiating a hashed container package with type String as the
36--  key. It is also useful as the generic actual equality operator when
37--  instantiating a container package with type String as the element,
38--  allowing case-insensitive container equality tests.
