Exotica HLT validation : latest developments

We monitor di-electron, single electron, di-photons, single photon, di-muon paths.
The validation plots are in general reasonable, although we still need to fix some features.
We plan to fix all features and fully fix our currently buggy trigger paths (others than the paths mentioned above) by our next pull request (should come at the end of next week).
This will be extremely useful to us to help further developments to have our current version integrated in the validation workflow.
