/*

This file just gives the basic definition of Slots. 

Callback# is the 4 byte data necessary for representing all
callback types.

CallData is a specific interpretation of the Callback data.

Slot_ is a pimple on SlotData containing an Object for
holding its referencees, a Dependency that removes the slot
when its caller or receiver die, and a Callback.

Slot is a handle to a Slot_.
