Add DOM state check to configure call

[chrissrogers]

configure should check the state of the stored fields and reset if the stored fields are no longer present.

@chrissrogers Any update on this? Currently developing a single-page app with Ember and am running up against this.

I see a parent option in configure. Is it possible to run configure again with parent: false to configure my form when it gets inserted into the DOM?

Hi @patcoll this is being addressed by #267

Multiple instances will allow destruction and re-instantiation of instances as desired. Once this goes in, however, I don't recommend doing so too much. Each instantiation requires each field to load an iframe, which incurs a noticeable load time. But it will allow for what you are requesting.

The parent option is used internally to track whether the r.js instance is running on the parent page or within an iframe.

@chrissrogers Funny enough I was just discussing a potential reset() method with some of your engineers :) Hadn't seen that PR.

Great information about the parent option, thanks. I hadn't looked too deeply into what that was for.

I will use multiple instances for now and will wait for this to land. Cheers!
