Inkblot Auth is a class that can authenticate users by showing them inkblot images. It can associate a given user password with a list of inkblot images. The user chooses the password after seeing a list of inkblots and types in what those inkblots look like. The class can authenticate the user after showing him the same inkblots in a random order and asking the user to type in what those inkblots look like.
