1. Update travis_setup.sh to start Fedora for testing.
2. Simple functional tests for Transcription Service (and later others) test:
   • Create Transaction & No other action & Commit Transaction (Commits nothing)
   • Create Transaction & State changing action & Commit Transaction
   • Create Transaction & Wait for time out and attempt to use confirm failure as expected
   • Create Transaction & Extent Transaction & Wait for time out and attempt to use confirm failure as expected
   • Create Transaction & State changing action & Extent Transaction & State changing action & Commit Transaction
   • Create Transaction & State changing action & Roll-back Transaction
   • Create Transaction & Extent Transaction & Roll-back Transaction
   • etc..
3. Add Documentation that PHPUnit can be use to test a Service, provide example (Perhaps later once we get the service layout figured out).

We'll move this into the CLAW repo, and this should partially address this ticket.
