**  ABSTRACT:
**
**      This module supports values in UIL.  UIL values are
**	quite primitive in terms of operators, however, there is a
**      concept of a private value that is local to this module
**      and a imported or exported value which needs to be
**	resolved via a lookup at runtime.  The runtime resolved values
**	cannot be modified with operators.
