Starterkit: Update line writing tutorial; Add prototype Bs -> Jpsi phi lines

The Line-writing session will be split in 2 parts

• Follow the tutorial with the example script; Run the example and inspect log file.
• The hands-on part will be to write a line for
  $B_s^0\to J/\psi \phi$
  , running it on MinBias, and later on
  $B_c^+ \to B_s^0\pi^+$
  signal MC to produce dsts for the sprucing and DaVinci sessions.

The documentation is updated to make a distinction between code used for the development and data-taking phase. The example has been updated accordingly.

A section on best practices has been added.

@mstahl thanks a lot for this I am enjoying the starterkit session on line writing enormously.

Does an example of how to run reconstruction (i.e. not read it from file) + run lines + print not only line but also reconstruction counters exist? Would it be useful to add it? When we end up running on real data to debug this summer I suspect this will be a quite common setup which we'll want to work from? (Yes this is my Run 2 nostalgia showing...)

probably some comments would be good.

I had tried that what confused me was that the tracking counters printed after the selection counters. Funny that the hybrid seeding doesn't print any counters as well. Anyway thanks!

Isn't this in principle https://gitlab.cern.ch/lhcb/Moore/-/blob/master/Hlt/Hlt2Conf/tests/qmtest/hlt2_pp_thor.qmt (modulo the reco counters part)? Is there a test checking explicitly the reco counters?

From the starterkit example, you can see in the timing table that PrHybridSeeding is running, but it indeed doesn't print any counters.

probably some comments would be good.

I agree. I should have talked more about the options file to run lines.
