Bugfix test memory leak

[dschlaep]

• Fix memory leak in nc-based test program: test's main() now checks for success of setup and, on failure, skips running tests and cleans up resources

• Option for automatic naming of domain template netCDF file (and avoiding early end of program)

  • Simulation program via command line option "-r"
  • Test program activates this option (and no longer fails if compiled with SWNETCDF flag if "domain.nc" didn't previously exist on path)
