Additional implimentations

### Mouse/Keyboard controlled light positions:
  #INSTRUCTIONS:
    1) press the number key corresponding to the camera to be controlled (1-9,0) -> light 1-9,10
    2) light will track mouse movements 
    3) up/down arrows to change light radius 

### Autosaved png images: 
  run with bash script above

### Anisotropic diffuse and specular shading:
  commandline -a

### Toon shading:
  commandline -q

### Outline:
  commandline -o 

### Perlin Noise Surface Texture:
  commandine - t

### Multiple Spheres:
  commandline -m
