greyhound v0.1.0 Greyhound.Middleware behaviour

Middleware is reponsible for processing dispatched events.

All event processing is handled by middleware. This allows Greyhound to provide a minimal event bus implementation while providing support for more complex event processing workflows.

See Greyhound.Middleware.Dispatch.Local for an example.
