file.
\param file The name of the file to deserialize.
\param error A pointer to a enum value recording if there was a problem
deserializing the diagnostics.
\param errorString A pointer to a CXString for recording the error string
if the file was not successfully loaded.
\returns A loaded CXDiagnosticSet if successful, and NULL otherwise. These
