/**
  
    Puzzling agent.
    
  
  This agent that plays a board game for one player.
  This example is a Jadex adaption of the original JACK(TM)
  puzzle example and was used for performance comparisons
  between both platforms (cf. readme.txt).
  This version shows how the puzzle works
  with a graphical board and uses a delay
  between the moves. Measurements were done
  with the Benchmark.agent in this package.
