-// This is the basic range generator interface.
-//
-// This base class provides all the API entry points, but only provides
-// functionality at the statement level.  Ie, it can calculate ranges on
-// statements, but does no additonal lookup.
-//
-// All the range_of_* methods will return a range if the types is
-// supported by the range engine.  It may be the full range for the
-// type, AKA varying_p or it may be a refined range.  If the range
-// type is not supported, then false is returned.  Non-statement
-// related methods return whatever the current global value is.
