This is a utility class to break the application at a point to inspect e.g. the result of
an algorithm.
You usually use it like this
\code
...
Base::Debugger dbg;
dbg.attach();
dbg.exec();
...
\endcode
Or you can connect it with a button and let the user click it in order to continue.
\code
QPushButton* btn = new QPushButton();
btn->setText("Continue");
btn->show();

connect(btn, SIGNAL(clicked()), &dbg, SLOT(quit()));
