  #
  # Done: 2.
  #   Write code that accomplishes the following (and ONLY the following),
  #   in the order listed:
  #
  #    - Constructs a SimpleTurtle with a  'blue'  Pen.
  #
  #    - Makes the SimpleTurtle go straight UP 200 pixels.
  #
  #    - Makes the SimpleTurtle lift its pen UP
  #         (so that the next movements do NOT leave a "trail")
  #         HINT: Use the "dot trick" to figure out how to do this.
  #
  #    - Makes the SimpleTurtle go to the Point at (100, -40).
  #
  #    - Makes the SimpleTurtle put its pen DOWN
  #         (so that the next movements will return to leaving a "trail").
  #
  #    - Makes the SimpleTurtle's pen have color 'green' and thickness 10.
  #
  #    - Makes the SimpleTurtle go 150 pixels straight DOWN.
  #
  #   Don't forget to:
  #     - import rosegraphics and construct a TurtleWindow
  #          at the BEGINNING of your code, and to
  #     - ask your TurtleWindow to   close_on_mouse_click
  #          as the LAST line of your code.
  #   See the beginning and end of m4e_loopy_turtles for an example.
  #
  #   As always, test by running the module.
  #   As always, COMMIT-and-PUSH when you are done with this module.
