* Add goro.Group Adds a goro.Group type intended to be used as a member field in objects that maintain one or more goroutines whose lifecycles are scoped to their own Start()/Stop() functions. * Covert matching.taskReader to use goro.Group Consistent with taskWiter we will use the goro package to encapsulate safe launch/stop of goroutines.
