[PROC] [SHAPE] Prepare Latinos Hands-On tutorial

[giorgiopizz]

The tutorial should be composed of two parts, both working with UL 2018v9:

1. Using processor, define two reasonable workflows for a double muon dataset and DY NLO
2. Using shape analysis create another example folder that works with latinos root files (as it is for 2016Real) that makes shapes for the DY CR in the double muon channel
