 ## Instructions
 - Drag to draw (improved dead-ends)
 - ctrl-click to add agent or select agent
  - if agent is selected:
    - ctrl-click to move agent position
    - use rotate agent to rotate 90°
    - ctrl-shift-click to set target for selected agent
      - target can be moved by repeating
 - to Resize the env (cannot preserve work):
  - select "Regen" tab, set regen size slider, click regenerate.
 - alt-click remove all rails from cell
