Add documentation on how to style the publishers and subscribers

[msach22]

When creating the publishers and subscribers, the library assigns the OTPublisherContainer and OTSubscriberContainer classes to their respective DOM elements.

@msach22
One problem is that OTPublisher and OTSubscriber have an anonymous div that can't be directly targeted with styling. See https://github.com/opentok/opentok-react/blob/master/src/OTPublisher.js#L173 and https://github.com/opentok/opentok-react/blob/master/src/OTSubscriber.js#L109
This makes it harder to use properties to set width:100%,height:100% on both OTPublisher and OTSubscriber. I'll send a PR...

Whats the status on this ^? I am running into the same issues

[michaellopez]

@coletivo This repo is basically not actively maintained. We worked around it by targeting the anonymous divs with CSS selectors
