  TODO / ideas list

  ########################################################################

  - Make Hogs sorted by rareness for teams with less hogs (more fair)

  - Keep first picked up unused crate utitlity until next round

  - Ship default scheme but let user overwrite it

  - Make SuddenDeathWaterRise dynamic

  - Make SuddenDeathTurns dynamic

  - Add Hog Variants like Crazy Scientist or Astronaut
