Migrate the relevant bits of AnalyzeAA.R from prototype-repertoire to alakazam. We may be able to rely heavily on the Peptides library instead of writing our own. Also, I think
translateDNA currently uses seqinr, which I'd like to get away from if possible. If not, no big deal.
Some additional examples using Peptides are at: https://bitbucket.org/javh/analysis/src/tip/oconnor_mg_memory/region_properties_2015-11-13.R?at=default&fileviewer=file-view-default
Also, we will need to write a vignette for this (which I guess is the hard part).
