Use TDD to drive the creation of a Car class that follows this interaction pattern:
car = Car.new("Toyota", "Camry")
#=> #<Car:0x007fc47816ba68 @make="Toyota", @model="Camry">
car.make
#=> "Toyota"
car.model
#=> "Camry"
car.color
#=> "white"
Use TDD to drive out the following behavior
car = Car.new("Toyota", "Camry")
car.color
#=> "white"
car.paint("blue")
car.color
#=> "blue"
car.odometer
#=> 0
car.odometer.class
#=> Integer
Use TDD to drive out the following behavior
car = Car.new("Toyota", "Camry")
car.horn
#=> "BEEEEEEEEP"
car.drive(12)
#=> "I'm driving 12 miles"
car.drive 6
#=> "I'm driving 6 miles"
car.odometer
#=> 18
Use TDD to drive out the following behavior
car = Car.new("Toyota", "Camry")
car.start
#=> "Starting up!"
car.start
#=> "BZZT! Nice try, though."
car.stop
#=> "Stopping"
car.stop
#=> "BZZT! Nice try, though."
car.start
#=> "Starting up!"
