 * Description: This is the Talk screen for ORBChat, a CORBA based chat program.
 *				This class uses SWING and implements a method called addText() which
 *				grabs the host name from the text field and sends it to the client to
 *				initialize a chat session. To run ORBChat, execute the Client.java class file.
