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 dispatcher Descriptor used by target classes to deliver the _Dispatch class at the class level and produce new _Dispatch instances for target instances.
Class Events Define event listening functions for a particular target type.
