Trying to make a universal version of sortbarcodes.py that can
work on any dataset.
* sortbarcodes-wobble.py is universal in that it can handle
  datasets with any wobble bits in the cutsite and any lengths
  of barcodes.
* sortbarcodes-indels.py has the added feature of allowing
  indels when calculating distance but at the cost of
  ability to handle datasets with wobble bits.
