CA tracking output QA updates

Updates:

• replacement of p with pT in acceptance histograms;
• new histograms:
  • Number of hits of reconstructed tracks (reco_nhits)
  • First station index of reconstructed tracks (reco_fsta)
  • Last station index of reconstructed tracks (reco_lsta)
  • #chi^{2}/NDF of reconstructed tracks (reco_chi2_ndf)
  • Time #chi^{2}/NDF of reconstructed tracks (reco_chi2_ndf_time)
  • MC Slope along x-axis of reconstructed tracks (reco_txMC)
  • MC Slope along y-axis of reconstructed tracks (reco_tyMC)
  • Azimuthal angle of MC track (mc_phiMC)
  • Polar angle of MC track (mc_thetaMC)
  • Polar angle vs. azimuthal angle of MC track (mc_thetaMC_phiMC)
