Notification Service

There is a use case where scientists should be notified when the experiment is aborted with hardware or software error. It requires a new GumTree component, so called the notification layer, to notify users on special event.

The GumTree server will also benefit from this framework. This will enable the server to send event such as reactor trip to live feed or mail.

The notification mechanism may include SMS, email, RSS, twitter, etc.

This framework is different from GUMTREE-395, where GUMTREE-395 is more like an internal application notifier, and this is the generic framework which will support the internal application notification mechanism as well as external notification like email.
