----------------------------------------------------------------------
10-nov-05    abb      Begun
22-jan-08    abb      Add support for YANG import and include
                      Unlike NCX, forward references are allowed
                      so import/include loops have to be tracked
                      and prevented
16-feb-08   abb       Changed environment variables from NCX to YANG
                      Added YANG_INSTALL envvar as well.
22-jul-08   abb       Remove NCX support -- YANG only from now on
06-oct-09   abb       Change YANG_ env vars to YUMA_
