Closes #155. Should we add more explanations here?
... and some other dead URLs
In some example scripts the name of the DST is outdated and does not match what's used in the earlier lessons, leading to a crash if executed blindly.
Since the twiki on grid storage quota is somewhat outdated, it should be useful to show the working instructions here.
In the [Exploring the DST lesson](https://lhcb.github.io/starterkit-lessons/first-analysis-steps/interactive-dst.html), it is mentioned the function > seekStripDecision (which replaces our advance) It is worth mentioning, that to reproduce the same behavior as of `advance(line)`,...
In the bookkeeping lesson, we talk about MC only. It is worth adding few words on how to find real data.
In the very end of [the lesson](https://lhcb.github.io/starterkit-lessons/first-analysis-steps/files-from-grid.html), 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-...
The [Introduction to LHCb software](https://lhcb.github.io/starterkit-lessons/first-analysis-steps/davinci.html) has several DaVinci versions in use in different places. We should stick to (the most recent) one - v42r6p1.
In the end of the [lesson](https://lhcb.github.io/starterkit-lessons/first-analysis-steps/dataflow.html), we mention the stripping line `D2hhPromptDst2D2KKLine` which is used in following lessons, however the link afterwards points to a wrong line. The proper link...
While we teach the data flow in LHCb, it is not explained how do we measure the momentum, perform a vertex fit or define the primary vertex. I had to...
