Merge pull request #322 from RosettaCommons/vmullig/goto_killer
Removing the last three goto statements in core
These really don't need to be here at all.
(To clarify -- by "removing", obviously I'm not just deleting them. I'm setting up the same program flow using other means.)
No test changes are expected, though I did see failures in tests that were already failing. I'll keep an eye on performance over the next little while -- I don't think this will affect performance in any way but the most negligible, but if it does, we can rework these.
