RxJS equivalent of async.parallel
var Rx = require('rx');
var zipper = function () {
// Turning arguments from an object into an actual array so we can use things like map()

};
var array; // Given some array of Observables that you want zipped together
// Or the more classical case where given an array of data to operate on, simply map them into observables
