/**\class edmtest::TestWriteTriggerResults
  Description: Used as part of tests that ensure the TriggerResults
  data format can be persistently written and in a subsequent process
  read. First, this is done using the current release version. In
  addition, the output file of the write process should be saved
  permanently each time its format changes. In unit tests, we read
  each of those saved files to verify that all future releases can
  read all versions of RAW data formats and Scouting data formats.
