<P>
Note: mapping from local to global is scalable; but global
to local may not be if the range of global values represented locally
is very large.
<P>
Note: the <A HREF="../IS/ISLocalToGlobalMapping.html#ISLocalToGlobalMapping">ISLocalToGlobalMapping</A> is actually a private object; it is included
here for the inline function <A HREF="../IS/ISLocalToGlobalMappingApply.html#ISLocalToGlobalMappingApply">ISLocalToGlobalMappingApply</A>() to allow it to be inlined since
it is used so often.
