+/** This base class describes an instance of a connection between a notification engine and ManifoldCF's
+* standard "pull" ingestion agent.
+*
+* Each instance of this interface is used in only one thread at a time. Connection Pooling
+* on these kinds of objects is performed by the factory which instantiates repository connectors
+* from symbolic names and config parameters, and is pooled by these parameters. That is, a pooled connector
+* handle is used only if all the connection parameters for the handle match.
+*
+* Implementers of this interface should provide a default constructor which has this signature:
+*
+* xxx();
+*
+* Connectors are either configured or not. If configured, they will persist in a pool, and be
+* reused multiple times. Certain methods of a connector may be called before the connector is
+* configured. This includes basically all methods that permit inspection of the connector's
+* capabilities.
+*
+*
+* The purpose of the notification connector is to notify people of job interruptions.
