Detailed Description

Ease loading nTuples generated with Gaussino into the SQLite event model of Lamarr.

As the other python data loaders, UprootLoader should be configured in the constructor. The configured object is then called during the event loop to pass the updated connection to the SQLamarr.SQLite3DB instance.

The ROOT file with path input_file is expected contain a TDirectory (named as configured with the collector keyword) with a TTree per SQLite table (the names of the TTrees are listed in tables) and each TTree should include a column (titled as indicated by batch_id_var) providing a unique identifier for the event number.
