// Tests for the sequence_journaled module.  Note that we only test journaled
// strings here.  In a perfect world, we would have tests for each atomic
// part of the module but for the moment, this has to suffice.  Instead of
// testing each of the many corner cases for the Journal Entries data
// structures, we rely on "fuzzying", i.e. executing a random set of
// operations and hope that all corner cases occur there.
