Iacuc tests, special review, protocol actions and species & procedures

Lots of tests for IACUC, @wips tags still need to be removed but there are a number of things that need to be reviewed and I assume there will need to be corrections to this pull request. 
This line is a bit ungrammatical. Can be changed to "When the creator adds..." by setting the step def's Regex up like this:

When /adds? two personnel members to the IACUC Protocol$/

In that way, the matcher ignores whatever is at the beginning of the string, and the 's' becomes optional.
