* Add Since tags where missing
* a few minor cleanups

One major item: FPR is not implemented correctly. Testing against only the
p-value and not the test statistic does not really tell you anything. We
should follow sklearn, which allows a p-value threshold for any selection
method:
[http://scikit-learn.org/stable/modules/generated/sklearn.feature_selection.SelectFpr.html]
* In this PR, I'm just going to remove FPR completely. We can add it back in a
follow-up PR.
