        Also remember, that CouchDB uses the Review-Then-Commit (RTC) model
        of code collaboration. Positive feedback is represented +1 from committers
        and negative is a -1. The -1 also means veto, and needs to be addressed
        to proceed. Once there are no objections, the PR can be merged by a
        CouchDB committer.

   ## Overview
   
   This refactors the couch_compress tests to allow them to run on platforms (e.g. s390x) where the compression output might be different to the fixed values defined in the tests. Namely:
   
    * Assert that compressed output is smaller than the input
    * Assert bigendian output is portable
    * Assert that compressed output can be re-compressed
   
   The first commit in the PR is a straight port of the existing couch_compress test fixture to ExUnit. The second commit makes the modifications described above.
