otb::DEMHandler not updated properly when resetting DEM-directory and/or Geoid-file.
Mantis Issue 1070, reported by salbert, assigned to salbert, created: 2015-09-15
When the user first enables then sets DEM-directory and/or Geoid-file, the otb::DEMHandler is initialized using ::OpenDEMDirectory() and/or ::OpenGeoidFile() which sets up the ossimElevationManager and/or ossimGeoidManager.
When the user then disables or clears the DEM-directory and/or Geoid-file, the DEMHandler is not updated in I18nCoreApplication::ElevationSetup() because there is no interface on otb::DEMHandler to clear the DEM-directory and/or Geoid-file.
