Callback executer wrapper.

execute.js

function execute(){
  var callbacks = Array.prototype.map.call(arguments, function(callback){
    return callback instanceof Function && callback;
  });
  return function(){
    var self = this;
    var args = arguments;
    callbacks.forEach(function (callback){
      callback.apply(self, args);
    });
  };
}

This is sort of like lodash _.flow but it doesn't pass the response to the next callback.
