Panda, tiger, eagle!

A few notes/questions:

• need help simplifying the specs with class variables
• noticed another student used self in the initialize, that would have simplified things
• added functionality to also update the class variable on each update
• added functionality to allow filter by any combination of attributes

this is the same as

def self.num_wheels
  2
end

Thanks for the feedback. I might try to work on a v2 of this at a later date to see I can grasp how to save the objects to @@all_vehicles.
