/**\class edmtest::TestReadRawDataBuffer
Description: Used as part of tests that ensure the RawDataBuffer
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 RawDataBuffer 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.
