+/***
+ * This class is used to construct a bare minimum
+ * acceptable header for an email message.  To construct more
+ * complicated headers you should refer to RFC 822.  When the
+ * Java Mail API is finalized, you will be
+ * able to use it to compose fully compliant Internet text messages.
+ * <p>
+ * The main purpose of the class is to faciliatate the mail sending
+ * process, by relieving the programmer from having to explicitly format
+ * a simple message header.  For example:
+ * <pre>
+ * writer = client.sendMessageData();
+ * if(writer == null) // failure
+ *   return false;
+ * header =
+ *    new SimpleSMTPHeader("foobar@foo.com", "foo@bar.com" "Just testing");
+ * header.addCC("bar@foo.com");
+ * header.addHeaderField("Organization", "Foobar, Inc.");
+ * writer.write(header.toString());
+ * writer.write("This is just a test");
+ * writer.close();
+ * if(!client.completePendingCommand()) // failure
+ *   return false;
+ * </pre>
