Rather than using 'begin_cb' rename it to a more suitable name. Further more instead of using the scope use the subscription to pass as an argument. The source scope is attached to the subscription when creating it so we can access it that way. This also adds a _complete and a _printf method for the subscription such that the callbacks can use to write data to only _that_ subscription and to close/complete it, otherwise writing to a scope results in writing to all subscriptions for that scope which is not correct. In the same time, the scope counter-parts of _write and _complete will now use the subscription function as well.
