/**
* The async function is a decorator for generator functions, turning
* them into asynchronous generators. Although generators are only part
* of the newest ECMAScript 6 drafts, this code does not cause syntax
* errors in older engines. This code should continue to work and will
* in fact improve over time as the language improves.
*
* ES6 generators are currently part of V8 version 3.19 with the
* --harmony-generators runtime flag enabled. SpiderMonkey has had them
* for longer, but under an older Python-inspired form. This function
* works on both kinds of generators.
*
* Decorates a generator function such that:
* - it may yield promises
* - execution will continue when that promise is fulfilled
* - the value of the yield expression will be the fulfilled value
* - it returns a promise for the return value (when the generator
* stops iterating)
* - the decorated function returns a promise for the return value
* of the generator or the first rejected promise among those
* yielded.
* - if an error is thrown in the generator, it propagates through
* every following yield until it is caught, or until it escapes
* the generator function altogether, and is translated into a
* rejection for the promise returned by the decorated generator.
