Documentation on how to implement <UIExpandingTableViewCell> protocol

[afanslau]

Ideally I shouldn't have to implement this protocol, it should just work with a UITableViewCell and I can modify the behavior by implementing the methods in the subclass. Please help in how to do this

[OliverLetterer]

I think you are absolutely right and I would gladly review and merge any pull request coming along :)

Once there is a change, I'll update the pod.
