instruction; it is present just so Python thinks you have a
syntactically-correct function definition for each method.

"""
Define a class called Car that
creates objects with
-- an x-position
-- a y position
-- an orientation (a float denoting an angle
let the angle be in radians (but if you really want degrees
use math.degrees(x) to convert x radians to degrees)
-- a speed (float) in miles per hour
Then define methods:
-- move(self,x,y): that moves the car to the point (x,y)
-- accel(self,factor): that adds factor to the speed (this accelerating or decelerating)
-- go(self,hrs): that moves the car where it would go in hrs hours. It has a speed and an orientation.
so it knows where to go!
-- __str__ should give a nice string that informs of the speed and orientation and location
-- rotate(self,ang) which adds ang to current angle
