* A VCard class for use with the
* <a href="http://www.jivesoftware.org/smack/" target="_blank">SMACK jabber library</a>.<p>
* <p/>
* You should refer to the
* <a href="http://www.jabber.org/jeps/jep-0054.html" target="_blank">JEP-54 documentation</a>.<p>

* Please note that this class is incomplete but it does provide the most commonly found

* <p/>
* <b>Usage:</b>
* <pre>
* <p/>
* // To save VCard:
* <p/>
* VCard vCard = new VCard();
* vCard.setFirstName("kir");
* vCard.setLastName("max");
* vCard.setEmailHome("foo@fee.bar");
* vCard.setJabberId("jabber@id.org");
* vCard.setOrganization("Jetbrains, s.r.o");
* vCard.setNickName("KIR");
* <p/>
* vCard.setField("TITLE", "Mr");
* vCard.setAddressFieldHome("STREET", "Some street");
* vCard.setAddressFieldWork("CTRY", "US");
* vCard.setPhoneWork("FAX", "3443233");
* <p/>
* vCard.save(connection);
* <p/>
* // To load VCard:
* <p/>
* VCard vCard = new VCard();
* vCard.load(conn); // load own VCard
* vCard.load(conn, "joe@foo.bar"); // load someone's VCard
* </pre>
