Add recursion option to smartDereference

[mindblight]

smartDereference won't attempt to dereference a dereferenced value. For example,

let store = {};

const jon = {
  id: 'user1',
  name: 'jon'
};
const jonReference = createReference('users', jon.id);
store = resolveReference(store, jonReference, jon);

const comment = {
  id: 'comment1',
  author: jonReference,
  comment: "something"
};
const commentReference = createReference('comments', comment.id);
store = resolveReference(store, commentReference, comment);

const blog = smartDereference(store, {
  title: "Some blog",
  comments: [commentReference]
});

// Should be jon, not jonReference
blog.comments[0].author === jonReference

User should be able to specify recursion depth. An infinite depth risks causing a stack overflow on a circular reference
