Detailed Description

This implementation of IPublisher sends its associated IDataProvider all requests and the final discard for the subjects defined by the associated INamespace.

The IDataProvider implementation must call Caplin.DataSource.Publisher.ISubjectPeerSubscriptions.PublishInitialImage to ensure that each requesting (subscribing) peer receives an initial image. Each call to PublishInitialImage sends the image to all peers that have requested the subject since the previous call to PublishInitialImage.

The IDataProvider implementation is responsible for keeping track of the number of requests received; it must only stop supplying data for a subject when there are no more peers subscribing to that subject.
