  # Dear Developer,
  #
  #   We closed another round of funding. Woot! I guess we're able to keep the
  #   the two of us around and the lights on for another few weeks before our
  #   next demo to our new masters...er, I mean investors.
  #
  #   We need to model airline seats so we can allow the booking agents to  put
  #   people in them. I started to build something but I wasn't able to finish
  #   everything and I am pretty sure THERE ARE BUGS. I would finish it but
  #   I am heading out to the big "Start Up Week" party.
  #
  #   Oh, yeah would you finish and fix this code for me?
  #
  #                                                 Sincerely,
  #                                                   Minimum Viable Developer
  #
  #   P.S. Aren't these company t-shirts so soft?
