Support for iframes

[james2406]

It looks like reselect-tools do not work if registerSelectors is called from an iframe. redux-devtools supports iframes through the isInIframe function:

I would be more than happy to work on a PR for this if that's okay with you.

Sounds good to me! Please do! Could you share a bit more about your use case so I understand?

I have a similar need for this; we have an application that uses a plugin interface where separately-hosted React apps are loaded in iframes.

Being able to debug the selectors from within the iframe would be very useful.

As a side note: I can't run these plugins without the parent application due to the plugins needing authentication information, which they can only get from the parent window.
