Trivial/Minimal cycle facility

This is trivial cycle KFacility merged with changes in 0.4.3. I don't have current working develop of cyclus, so this is for review and comments only.
The original integration tests for this scenario are broken due to some changes in output tables.
I am suppressing DbInit parts because I am assuming they are not relevant to integration tests or will be auto generated with pragmas. Correct me if they are still needed.
