  Generate a set of hub sequences. These are sequences which contain a hub

  Parameters:
  -----------------------------------------------
  nCoinc:        the number of elements available to use in the sequences
  hubs:          which of the elements will be used as hubs.
  seqLength:     a list of possible sequence lengths. The length of each
