IRB Code for test KRAFDBCK-9927

test mostly complete, added some helpful functions for Expedited Approval 
Some problems, here:

1) You've made this a parameterized method, but aren't using the parameter in the code block
2) If it is actually a parameterized method you should use p_value instead of value
3) What's the difference between this method and the "locked value" version above?  Can we make an # expedited_approval_date method that works for all three situations? We should try to minimize the number of similarly named methods whenever possible.
