1. How to use

   Dispatcher = 'node-dispatcher'
   dispatcher = new Dispatcher
   dispatcher.use *id*, *function*
   
   if dispatcher.isMaster
       dispatcher.fork()
       dispatcher.pushQ *id*, *target*
       dispatcher.on 'result', (message) -> message.result = *function*( *target* )
   

2. Master

   1. Properties
      • isMaster -> if dispathcer is master return true else false.
      • isWorker -> if dispathcer is worker return true else false.
      • pid -> return pid of instance.
   2. Methods
      • fork() -> make instance of worker.
      • forks(n) -> make n instances of worker.
      • use(id, function) -> register id and function (typeof id is 'string').
      • pushQ(id, target) -> push id and target on Queue.
      • remove() -> exit all workers which is working.
   3. Events
      • on 'pullTask',(message) -> message.pid is the pid of worker which pull task.
      • on 'result', (message) -> message.result is result of task, message.task is task.
      • on 'workerStart', (message) -> message.pid is the pid of starting worker.

3. Worker You can not customize Worker or touch on them, because Workers are precious for them and do not push everythig against them.
