Create an instance of the class "EventsWaiter".

var waiter = new require('events-waiter')

Register events on the method "#addEvent".

waiter.addEvent("event_1");
waiter.addEvent("event_2");
waiter.addEvent("event_3");

Call the method "#wait(callback)" for the start events waiting. Pass the callback function in this method as option. The callback will be called when all events are completed.

waiter.wait(function(){});

waiter.completeEvent("event_1");
waiter.completeEvent("event_2");
