That depends on what we want we want cel-cookie to do.  If we want it to simply be our own mini-api for accessing our cookie data then we should leave logic for dealing with favorites out of it and put it somewhere else.  If we want to wrap the cookie logic into the favorites logic, we should probably just move all the favorites logic there and rename it to favorites.js or something.  I'm kind of apathetic about which way we go on it though.
