/**\class edmtest::TestWriteFEDRawDataCollection
  Description: Used as part of tests that ensure the FEDRawDataCollection
  data format can be persistently written and in a subsequent process
  read. First, this is done using the current release version for writing
  and reading. In addition, the output file of the write process should
  be saved permanently each time the FEDRawDataCollection persistent data
  format changes. In unit tests, we read each of those saved files to verify
  that the current releases can read older versions of the data format.
