-# SUMMARY OF THIS TEST
-# ...................
-# Author: P.Seyfert
-# Purpose: * Check that DaVinci can perform a track fit
-#          * This validates the existence of clusters in the input file
-#          * Furthermore, check the compatibility of the DaVinci track fit result with the Brunel fit result
-# Prerequisites: an input file, I guess? (work in progress)
-# Common failure modes, severities and cures: 
-#          . MAJOR: * Fits fail due to missing raw data (lite cluster unpacking)
-#                     -> figure out if the input file really contains the clusters it's supposed to contain
-#                   * Fit results incompatible
-#                     -> Check input variables in ntuple (are we discovering packing precision or are integer values off)
