Waiting for a condition before render

[rogchap]

Would be great to incorporate WaitFor.js (https://github.com/ariya/phantomjs/blob/master/examples/waitfor.js) into mean-seo.

This Phantom.js script waits until the test condition is true or a timeout occurs.
Useful for waiting on a server response or for a ui change (fadeIn, etc.) to occur.

I'm happy to look into this, but just making sure someone else is not already working on this?

yes please,
This module is currently not working with dynamic data (get via api asynchronously then render to UI, etc.).
Could we wait for an event to make sure page rendered completely before taking a snapshot?
(ex: wait for attribute "loaded" in body tag)
