For shape matching, I am displaying a contour viewer similar to CV_Contour.
However, all non-matching contours are colored red and a matching contour
will be colored green. An image of the shape I matched with is also provided
in the zip file for convenience. Note that the jpg file has to be fairly clear
and well lit as shadows will cause problems in matching accurately.

For speech recognition, the commands have the following nuances:
    World Listing: For objects with an is_visible property cozmo only lists
    them if they are currently visible. For other objects they are listed if
    they are in the world_map

    Cube Grabbing: Cozmo picks up said cube (but does not put it down). I was
    unsure what exactly was meant by grabbing but this action seemed
    appropriate

    Doorway Driving: Cozmo will complain in different manners for an invalid
    door and non-visible but possibly valid door (aka if the number cannot be
    parsed correctly)
