Updates to Alignment

Merged Simon Spannagel requested to merge alignment into master

This MR

  • corrects a mistake in calculating the alignment shifts for each iteration

  • improves printout dramatically (units etc)

  • moves to using local residuals for minimization for single detectors

  • adds the possibility to prune tracks before selection for alignment. This includes

    • cut on the track's chi2ndof value
    • cut on the number of associated clusters

    both only really make sense for singe detector alignment (residual method)

  • updates all alignment plots to be actually useful

Missing:

  • document new features and parameters.
  • cross-check dY/X etc profiles.
