Module for analysing the Material Budget of a scatterer

This new module AnalysisMaterialBudget aims to analyse the position-dependent kink angle of tracks at a scatterer, creating kink angle distributions and a Material Budget Image with variable sizes of the image cells or the image itself.

The Material Budget Images show the width of the kink angle distribution of all particles traversing a given image cell. At this point, no attempt is made to translate this width into the actual material budget (x/X0), given the fact that the absolute values strongly depend on the detector setup and the detector resolution and include scattering in air and neighbouring detectors. For this, a calibration would be required for every individual setup.

Currently, this only works when using tracks of the type Multiplet, since it is the only track model allowing for kinks at a position without detector. In the future, it could possibly be extended to support GBL tracks, evaluating the kink angles at a certain detector plane.
