Avoid just-in-time compilation when not needed * inst/private/check_hash.m: check whether the previous compilation used the same ufl file * inst/private/save_hash.m: save to disk ufl file's md5sum for future comparison * inst/private/check_oct_files.m: ensure the expected oct files are present * inst/import_ufl_*.m: add checks using the logic above
