Cosmetic changes for CaloL2 offline DQM

[jimbrooke]

@kreczko @tapperad

Here are some proposed changes to CaloL2 DQM. First, the easy ones

• ensure all plots binned by offline pT have an overflow bin (this might already the case ?)
• extend x-axis range of efficiency plots to include all available bins in numerator/denominator

Then some about organisation of plots in folders, since it is currently tricky to know where to look. This is just a proposal, feel free to comment!

• I suggest something like arranging them by object type under L1T. ie. L1T/Jet, L1T/EGamma, L1T/Tau, L1T/Sum etc. (or L1T/L1TJet etc. if preferred).
• within each object folder, arrange by plot type, eg. L1T/L1TJet/Correlation, L1T/L1TJet/Efficiency, L1T/L1TJet/Resolution.
• the efficiency_raw plots could go in L1T/L1TJet/Efficiency

Last point is about reference plots - it would be good to find out how to upload them, since we can identify a reference run easily and start making use of this right away.

We should discuss the directory structure with @bortigno and @zabi but the other points I have discussed with Jim and should go ahead please.

The muon guys (Thomas Reis et al.) know how to add reference plots if we do not.
