/**
* \brief The Application class provides an event loop for console applications
* without a GUI.
*
* This class is used by non-GUI applications to provide the applications's event
* loop. There should be only exactly one instance of Application (or one of its
* subclasses) per application. This is not ensured, though.
*
* Application contains the main event loop, where event sources can be registered
* and events from those sources are dispatched to listeners, that were registered
* to the event loop. Events may for example be operating system events (timer, file
* system changes).
*
* The application and therefore the event loop is started with a call to run() and
* can be exited with a call to exit(). After calling exit() the application should
* terminate.
*
* The event loop can be access by calling eventLoop(). Events can be committed by
* calling EventLoop::commitEvent(). Long running operations can call
* EventLoop::processEvents() to keep the application responsive.
*
* There are convenience methods available for easier access to functionality of
* the underlying event loop. commitEvent() delegates to EventLoop::commitEvent(),
* queueEvent() delegates to EventLoop::delegateEvent() and processEvents() delegates
* to EventLoop::processEvents() without making it necessary to first obtain the
* event loop manually.
