Added the Temperature Graph.

Browse source 
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.
