Developer notes


Simulation completed on 4 Nov:

1. Vernier Caliper

    - enlarged the dragme objects on the bottom scale (yellow) and bottom object (blue) to help make the dragging easier on smaller mobile screen

    - added "mm" on top scale

    - added checkAndroid for fullscreen

    - removed bug for initial tail values (yellow) when measuring depth. (so that yellow tail won't "pierce" through the pink container.
