"Series" Aircraft

Some manufacturers, like Cessna, changed model numbers throughout the production of an aircraft.  For instance, the 150 was manufactured as the 150, the 150A through 150H, 150J through 150M, and the A150K through A150M.  I have decided to create a "series" page for all of these, so that there will only be one entry under Cessna 150, instead of listing all of the different submodels.
