+
+    Starts an event loop that runs until the given signal is received

+
+    \a timeout is any valid std::chrono::duration (std::chrono::seconds,
+    std::chrono::milliseconds ...etc).
+
+    Returns \c true if the signal was emitted at least once in \a timeout,

+        QSignalSpy spy(object, signal);
