adding custom getter in the FlavorTagDiscriminants package
This MR is adding a custom getter for the variable log_z0RelativeToBeamspotUncertainty
within the package PhysicsAnalysis/JetTagging/FlavorTagDiscriminants
. This variable is required for the usage of neural networks for b-tagging.
This implementation was tested within the training-dataset-dumpster following @dguest suggestion.
