* @brief Finds the first Client matching the condition expressed by passed in @p func.

* @code
* xcb_window_t w; // our test window
* Client *client = findClient([w](const Client *c) -> bool {
* return c->window() == w;
* });
* @endcode
*
* For the standard cases of matching the window id with one of the Client's windows use
* the simplified overload method findClient(Predicate, xcb_window_t). Above example
* can be simplified to:
* @code
* xcb_window_t w; // our test window
* Client *client = findClient(Predicate::WindowMatch, w);
* @endcode
*
* @param func Unary function that accepts a Client* as argument and
* returns a value convertible to bool. The value returned indicates whether the
* Client* is considered a match in the context of this function.
* The function shall not modify its argument.
* This can either be a function pointer or a function object.
