       These are the generic error codes. The same error code is used in
     many different places in the code.

       In addition, each specific error in the code has an error
     message: an a unique specific eroror code.  (The specific error
     code is not yet in use, those will be generated automatically and
     embed an integer into the PetscError() calls. For non-English
     error messages that integer will be extracted and used to look up the
     appropriate error message in the local language from a file.)
