Task-Executor

Execute a series of tasks in a simple linear way without annoying callback functions.

Example:

// create a task that can complete sth.  
var task = new Task(function(ctx, callback) {  
    console.log('Hello World!');  
    callback();  
});

// get a TaskQueue instance.  
var queue = TaskQueue.getInstance();

// add some tasks into the queue.  
queue.log('begin').add(task);  
queue.wait(1000).log('wait for 1 second').add(task);  
queue.log('end');

// execute the tasks.  
queue.execute();
