Walk Profile and satistics (Profile et statistiques de la balade)

Distance, max and min altitudes, accumulated climb; time of start and end of walk.
There are often significant differences between alttitudes, and changes of altitude, as measured by a GPS and as calculated by cartography software. The latter is more accurate, since the GPS system does not have a high degeree of precision for the vertical axis.
