Added a Model that should handle the Dive Profile
This model encapsulates the plot_info struct and provides a consistent way to show it using the Qt Model view system in the C++ and QML way. For a QGraphicsItem that should show a Profile, this is the start. Signed-off-by: Tomaz Canabrava <tcanabrava@kde.org> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
