IRB Code for test KRAFDBCK-9927

test mostly complete, added some helpful functions for Expedited Approval 
This scenario has a number of problems:

- It needs a Committee defined because the IRB Protocol has to be submitted to a particular committee, otherwise the scenario can't work
- The step that talks about the creation of the protocol is inter-mingling the submission of the protocol to the committee, but the submission doesn't happen until the next step.  That's going to be a problem.

I think the right thing to do is to create a single step def that combines all those things into one:

"the IRB Admin submits a Protocol to the Committee for Expedited review, with an approval date of last year"

- You have a Then step occurring before a When. This isn't valid Cucumber. There should be one pivotal event per scenario.

Please talk to me about this stuff if you have questions.
