* New tool BGPredict predicts background noise profiles (containing
  only stutter products) for user-supplied alleles/sequences using
  a trained stutter model obtained from Stuttermodel. Currently
  only the amounts of the forward strand are predicted.
* New option -L/--min-lengths for Stuttermodel allows to set a
  minimum required number of unique repeat lengths to base the
  fits on (default: 5).
* Updated formatting of output of Stuttermodel: added '+' sign to
  positive stutter, limited r2 scores to 3 decimal places, and now
  all coefficients are written in scientific notation with 3
  decimal places.
* The --output-column option of SeqConvert now defaults to using
  the value of --allele-column.
