Smithy Applet (early prototype)

There are two copies because smithy applets are wired to a second Treehouse applet. These two are wired to each other, but in the future the second applet could be any scriptable Treehouse program.

Implmented thus far:

• Scan on each applet to discover programmable modules.
  
• Make a reference to a module and move it to the workspace or on the wheel.
  
• Run and pause.
  
• Discard removes a refrence or a module. Discarding a module also removes all related references.
  
• Discarding modules works across programs.
