ValueInteractor

A ValueInteractor object allows multiple influences to act on the same piece of data without overwriting the effects of each other.  By simply allocating and initializing them with their initializers they attach themselves to the data that you provide.  Each ValueInteractor object keeps a kind of pseudo history of its interaction with the data and will change the data according to the deltas of where it thinks it should be at instead of just setting the data to the value.  This allows other ValueInteractor objects to affect the data without interfering and being interfered with.  The responsibility for them is held by the allocater instead of the system unlike Timers and EventReceptors which are tied to the existence of the objects that they interact with.  Their spec and usage are currently in flux right now.
