/** A client-side proxy.
 * This is a base class used for proxies to access a D-Bus interface on
 * a remote object. It can be constructed for both well-known and
 * unique names.
 *
 * By default, Proxy will cache all properties (and listen to changes) of
 * the remote object, and proxy all signals that gets emitted. This behaviour
 * can be changed by passing suitable ProxyFlags when the proxy is
 * created. If the proxy is for a well-known name, the property cache is
 * flushed when the name owner vanishes and reloaded when a name owner
 * appears.
 *
 * If a Proxy is used for a well-known name, the owner of the name is
 * tracked and can be read from property_g_name_owner().
 *
 * The generic signal_g_properties_changed() and signal_g_signal() signals are
 * not very convenient to work with. Therefore, the recommended way of working
 * with proxies is to subclass Proxy, and have more natural properties and
 * signals in your derived class.
 *
 * This documentation was adapted from the C API documentation.  The C API docs
 * has more information and an example.
