* <p/>

* This method matches the same kinds of fields that are returned by {@link Class#getDeclaredFields()} with the

* exception that it includes fields inherited from the superclasses. This means public, protected, default

* (package) access, and private fields AND fields of those types inherited from the superclasses.
