//! \class XMPP::Client client.h
//! \brief Communicates with the Jabber network.  Start here.
//!
//!  Client controls an active Jabber connection.  It allows you to connect,
//!  authenticate, manipulate the roster, and send / receive messages and
//!  presence.  It is the centerpiece of this library, and all Tasks must pass
//!  through it.
//!
//!  For convenience, many Tasks are handled internally to Client (such as
//!  JT_Auth).  However, for accessing features beyond the basics provided by
//!  Client, you will need to manually invoke Tasks.  Fortunately, the
//!  process is very simple.
//!
//!  The entire Task system is heavily founded on Qt.  All Tasks have a parent,
//!  except for the root Task, and are considered QObjects.  By using Qt's RTTI
//!  facilities (QObject::sender(), QObject::isA(), etc), you can use a
//!  "fire and forget" approach with Tasks.
//!
//!  \code
//!  #include "client.h"
//!  using namespace Jabber;
//!
//!  ...
//!
//!  Client *client;
//!
//!  Session::Session()
//!  {
//!    client = new Client;
//!    connect(client, SIGNAL(handshaken()), SLOT(clientHandshaken()));
//!    connect(client, SIGNAL(authFinished(bool, int, const QString &)), SLOT(authFinished(bool, int, const QString &)));
//!    client->connectToHost("jabber.org");
//!  }
//!
//!  void Session::clientHandshaken()
//!  {
//!    client->authDigest("jabtest", "12345", "Psi");
//!  }
//!
//!  void Session::authFinished(bool success, int, const QString &err)
//!  {
//!    if(success)
//!      printf("Login success!");
//!    else
//!      printf("Login failed.  Here's why: %s\n", err.latin1());
