Detailed Description

This class provides a request/reply facility for messaging over a topic.

We recommend that clients follow these steps:

Create a TopicSession, and use it to create a Topic for requests and replies.
Create a TopicRequestor, using the topic session and Topic as arguments.
Send a request and receive a reply. You may repeat this step for several request and reply pairs.
Close the requestor object, when done. The Close method also closes the requestor's session as a side effect.
