Tablespaces organized and scaled according to their allocated size

Finally, my tablespaces look good. The size of the "container" is proportional to the allocated size of the tablespace:



Also I've included picking feature to be able to select one tablespace and (in the future) get detailed information. However, I note right now that the BoundingBox class that I use for bounding volumes (mainly used for collisions detection and picking) is not very good for cylinders...
