Simple utility to queue callbacks in a pool until the drain has been unplugged.
npm install callback-pool --save
##Example
var pool = require('callback-pool');
var myPool = pool.create();//creates a new pool
//these are queued up
myPool.add(function(a, b){console.log('foo');});
myPool.add(function(a, b){console.log('boo');});
myPool.drain(1,2);//all callbacks are executed asynchronously with 1 and 2.
//these are now asynchronously executed immediately with 1 and 2
myPool.add(function(a, b){console.log('execute me');});
myPool.add(function(a, b){console.log('me too');});
myPool.plug();//allows you to start over.
