Title: Add note about hiding relationships using method name instead of accessor

Caught me out for a bit.

In toArray() the relationship will be under the `authored_by` key, however to hide it we need to add `authoredBy` to `$hidden` instead (method name, instead of accessor).

See laravel/framework#373
