Functions
bool	waitForService (const Node &_node, const std::string &_service, std::chrono::milliseconds _timeout=std::chrono::milliseconds(10000))
	Block until a service is discovered or a timeout expires.
void	waitForShutdown ()
	Block the current thread until a SIGINT or SIGTERM is received. Note that this function registers a signal handler. Do not use this function if you want to manage yourself SIGINT/SIGTERM.
bool	waitForTopic (const Node &_node, const std::string &_topic, std::chrono::milliseconds _timeout=std::chrono::milliseconds(10000))
	Block until a topic is discovered or a timeout expires.
template<typename Pred >
bool	waitUntil (Pred _pred, std::chrono::milliseconds _timeout=std::chrono::milliseconds(10000), std::chrono::milliseconds _interval=std::chrono::milliseconds(10))
	Block until a predicate becomes true or a timeout expires. Polls by calling _pred() repeatedly with _interval sleep between checks. Uses steady_clock for monotonic timing.
