Draw the finite state machine by drawing circles and connecting 
edges.  Draw a circle around a node to make it an accept node.
Draw 0 or 1 next to edge to change its name.

Things you can say:
      "How Many Nodes Are There?"
      "Delete Node A"
      "Delete that"
      "Delete that edge"
      "Delete that node"
      "Undo that"
      "Redo that"
      "Name node A"
      "Name that edge"
      "Name that edge 0 or 1"
