Program behavior

The first four programs populate a new world with a parking meter and an ice skater.

Program execution will consist of the following actions in sequence:

• Align the ground, the parking meter, and the ice skater with the viewpoint of the world.
   
• Set the camera to a known viewpoint.
   
• Set the ice skater to her starting viewpoint.
   
• Animate the skater's left leg and foot to cause her to lift her lower leg and point her toes away from her.

The last two programs will emphasize improvements in the animation of the skater
