Examples of NewsService

org.rssowl.ui.internal.NewsService
An internal Service helping Viewers to deal with the presentation of INews. Current implemented features:
- Fast access to Unread-Count of News from a Feed
- Fast access to New-Count of News from a Feed
- Fast access to Sticky-Count of News from a Feed
TODO Introduce a Listener that allows others to register on changes to one of the fields. This reduces possible errors in case some plugin manages to register as News-Listener right before this service.
