Permutation is a precise definition on how elements within index range should be reorganized

Consider ordering a buffer of integers. This could be accomplished it two steps:

1. Based on some Ordering, we create a Permutation object, which captures all necessary positions
2. Apply permutation to the buffer

  val buf = Stream(0, 3, 1, 2, 4).toBuffer

  buf.stream.tp // Prints:  Stream(0, 3, 1, 2, 4)

  // Creating permutation based on given ordering
  val p = Idx.Permutation.sorting(buffer)

  p.tp               // Prints: Permutation{range=1 <>> 4,(1,3)(2,1)(3,2)}

  p.reposition(buf)  // Applying permutation

  buf.stream.tp           // Prints Stream(0, 1, 2, 3, 4)
