ECMA-6 Promises polyfill
100% compliant Promises/A+ implementation, and as close as possible to the ES6 Spec.
This polyfill can be used as a stand-alone or together with the hAzzlejS Javascript library.
Be aware that ECMA-6 already have been on the table for some years now, and ECMA-7 are sneaking in the shadows, so the specs will change again and again...
Note!! For better performance you should load the ECMA-6 setImmediate polyfill first, else it will fall back to a normal timeOut.
