It can be useful to get the amino acid properties for the different regions
Jason Vander Heiden
The problem I foresee with this is that RegionDefinitions are part of shazam, and shazam depends on alakazam, not vice versa. So we'd have to move RegionDefinition into alakazam.
Hrm. alakazam::extractVRegion can accomplish this task already, so it would probably be better to have an argument to pass the sequences through extractVRegion before calculation instead of using RegionDefinition objects.
