Added the Temperature Graph with its related classes. A Temperature Axis is also created so the item is plotted on the right place. Currently the Temperature Axis is just like the depth axis - top is zero, wich means that the graph is inverted. Also, the Temperature axis is being displayed as this helps debugging.
