*** PLEASE READ BEFORE STARTING THE ASSIGNMENT, Version A ***

NOTE: If you have not read the assignment notes yet, we recommend that
      you do that BEFORE you read this. All of the math discussed here
      is explained in the assignment notes.

    In this assignment, you will be using tools that we provide for
    you to build/load a scene and render the scene. These tools have
    been built and blackboxed so do not worry about the implementation
    details and instead focus on learning how to use the tools.

    If you are curious as to how everything fits together behind the
    scenes, feel free to read through the files but it may be time
    consuming.

/************************* Terminology ********************************/

Primitive: we call superquadrics "geometric primitives" in our program

Assembly: we group superquadrics as "Assemblies." Assemblies have
          children Assemblies and Primitives. The end goal of this
          assignment is to select an Assembly model in the command
          line and raytrace it.

Renderable:  we call Primitives and Assemblies Renderables as a whole.
            as the name suggests, essentially anything we're going to
            render can be called a Renderable

   Version B needed much more information in this section, which we
   don't need for Version A.
