EXOT27: Switching to completely specified trigger lists. Allowing one muon events through.
Using the trigger API directly includes many extra triggers that we aren't actually interested in unfortunately, inflating the size of the derivation unneccessarily. We also realised that we need the one muon events included to derive our MET trigger scale factors. Previously these events were being lost.
This was tested and the size on my test data file is now exactly 1%.
