In AliMUONTrackExtrap: - Change the Bethe-Bloch formula for mean energy loss correction (use the new    one provided in STEER like other detectors)    --> about same results for upsilon    --> better results for J/psi - Improve the computation of mean excitation energies + a few minor corrections (Philippe P.)
