Defines an entry in the tmnxOamTrResultsTable. The
first two indexes of the tmnxOamTrResultsTable are the
same as the tmnxOamTrCtlTable in order for a tmnxOamTrResultsEntry
to correspond to the tmnxOamTrCtlEntry that caused it to
be created. The third index allows a history of test runs
to be stored.
