//@todo review this. I'm not sure if this is the best strategy here, but I'd like for the ability
//to pass some information to the implementer of traits. I.E. For logging in, the implementer
//probably wants the IP of the connection that is attempting to log in, so that they can rate limit
//or ban. Further, for share submitting and other features, the implementer probably wants the same
//ability. Rather than pass the entire stream into the trait functions, I figured we should build a
//struct that holds some information about the miner that can be edited and passed into those
//functions.
