Detailed Description

Some region_model activity could lead to warnings (e.g. attempts to use an
uninitialized value).  This abstract base class encapsulates an interface
for the region model to use when emitting such warnings.

Having this as an abstract base class allows us to support the various
operations needed by program_state in the analyzer within region_model,
whilst keeping them somewhat modularized.
