Base implementation classes.

The public-facing Events serves as the base class for an event interface; its public attributes represent different kinds of events. These attributes are mirrored onto a _Dispatch class, which serves as a container for collections of listener functions. These collections are represented both at the class level of a particular _Dispatch class as well as within instances of _Dispatch.

Class ​Events Define event listening functions for a particular target type.
Class _​Dispatch Mirror the event listening definitions of an Events class with listener collections.
Class _​Event​Meta Intercept new Event subclasses and create associated _Dispatch classes.
Class _​Joined​Dispatcher Represent a connection between two _Dispatch objects.
Class _​Unpickle​Dispatch Serializable callable that re-generates an instance of _Dispatch given a particular .Events subclass.
