This RFC proposes extensions to the Sawtooth SDK's to support event processing. These events are emitted by the validator on block commits and can be subscribed to via client messages. These SDK extensions propose a simplified abstraction on top of these client messages in order to provide a simple model for handling the events. This API is akin to the Transaction Handler/Transaction Processor API's. Signed-off-by: Peter Schwarz <pschwarz@bitwise.io>

[Thinking out loud]: Can this be trait object passed to a function like "with_filter()", where is either regex or simple or something else coming up later.
Fix code snippet for proper syntax highlighting. Signed-off-by: Peter Schwarz <pschwarz@bitwise.io>

I assume this documents existing event handling. I see where you describe creating a subscription, then you jump to event handling. Missing is any description of how/where to send the subscription, and an API to listen to the event subscription response.
A Rust example would be nice.
