Wrong DST in the Downloading files from grid lesson

[vlisovsk]

In the very end of the lesson, the callout box 'such a clever script' points to the file MC_2012_27163003_Beam4000GeV2012MagDownNu2.5Pythia8_Sim08e_Digi13_Trig0x409f0045_Reco14a_Stripping20NoPrescalingFlagged_ALLSTREAMS.DST.py

It is a remnant from the times when we used D0->K+pi- decay in our examples. This path needs to be changed to MC_2016_27163002_Beam6500GeV2016MagDownNu1.625nsPythia8_Sim09b_Trig0x6138160F_Reco16_Turbo03_Stripping28NoPrescalingFlagged_ALLSTREAMS.DST.py already mentioned above on the same page.
