title: How to implement ordered crossover
body: <p>So I have two parents
  ABCDE
  EDCBA</p>
  
  <p>can I just select a subset from both:
  From parent one: ACD
  From parent two: EDC</p>
  
  <p>Then I copy parent one into offspring one but copy the selected subset with parent twos order so:
  Offspring one: DBCAE
  Offspring two: CDEBA</p>
