As Bob keeps its trajectory to serve more types of systems, it becomes less and less obvious to keep biometrics-related functionality inside this package. I'm proposing we move those into `bob.bio.base`, which is the place they should have been in the first place. A few things that come to mind: * All score loading/saving functionality * OpenBR exchange support * The scripts, which are tunned for Biometrics-style reporting (and can only load biometric score files) * Not sure about all the identification stuff, maybe generic enough to keep here? Thanks for your feedback.
