DNA barcode utilities
1. Find a consensus sequence for a species
2. Find pairwise divergence for two specimens (source is an aligned fasta file from AliView)
2a. Find pairwise divergence for many specimens (source is an aligned fasta file from AliView)
3. Find diagnostic sequence positions for a species relative to more than one relative (source is an aligned fasta file from AliView)
4. Simplify a file so that it can run in SpeciesIdenfitier (organizes identical sequences into groups)
