/**
 YYTimer is a thread-safe timer based on GCD. It has similar API with `NSTimer`.
 YYTimer object differ from NSTimer in a few ways:
 
 * It use GCD to produce timer tick, and won't be affected by runLoop.
 * It make a weak reference to the target, so it can avoid retain cycles.
 * It always fire on main thread.
