Client Library Desires to Register with the HDF5 Error API:
- Client library registers itself with the HDF5 error API, receiving
an "error class ID" for future error API operations for that library.
- Client library uses its error class ID to register major and minor
error types and their descriptions, receiving an ID code for
each error type registered.
- Major and minor error types may be registered at any time during the
execution of an application.
