Combination with repetition

[PhilWaldmann]

combinations with repetition are currently not supported, right? Something like that would be awesome!

Combinatorics.combinationWithRep(['a', 'b', 'c'], 4)
/*
=> [ 
  [ 'a', 'a', 'a', 'a' ],
  [ 'a', 'a', 'a', 'b' ],
  [ 'a', 'a', 'a', 'c' ],
  [ 'a', 'a', 'b', 'b' ],
  [ 'a', 'a', 'b', 'c' ],
  [ 'a', 'a', 'c', 'c' ],
  [ 'a', 'b', 'b', 'b' ],
  [ 'a', 'b', 'b', 'c' ],
  [ 'a', 'b', 'c', 'c' ],
  [ 'a', 'c', 'c', 'c' ],
  [ 'b', 'b', 'b', 'b' ],
  [ 'b', 'b', 'b', 'c' ],
  [ 'b', 'b', 'c', 'c' ],
  [ 'b', 'c', 'c', 'c' ],
  [ 'c', 'c', 'c', 'c' ] 
 ]

baseN essentially does this, just not in the order you are indicating
