Document creating multiple pollers in single injection

[rayshan]

Hi, thanks for the module, it's very well done and full-featured. May I recommend documenting how to create multiple instances for multiple resources within a single injection? E.g.:

var myPoller1 = new poller.get(myResource1);
var myPoller2 = new poller.get(myResource2);

Then poller.stopAll() would make more sense and one can use $q.all() and map the responses.

Hi Ray, thank you for your feedback! I have updated the document based on your suggestion.

Unfortunately you can not use $q.all with multiple pollers since Angular does not support notification forwarding for $q.all yet: angular/angular.js#2223 (comment).

Thanks Emma! And that was a good read. $q needs a lot of work (angular/angular.js#5223), but now that ES6 is coming and Q's API differs from the standard (http://www.html5rocks.com/en/tutorials/es6/promises/#toc-javascript-promises), I wonder if they'll refactor the pollyfill with something like RSVP.js.
