//       Class : DCDeclaration
// Description : This is a common interface for a declaration in a DC
//               file.  Currently, this is either a class or a typedef
//               declaration (import declarations are still collected
//               together at the top, and don't inherit from this
//               object).  Its only purpose is so that classes and
//               typedefs can be stored in one list together so they
//               can be ordered correctly on output.
