> setValue methods in Field and subclasses should introduce type safety, beacuse what is now possible is to instantiate a BinaryField and set a non-binary value, but introduce it in such way to be able to preserve the ability to yield setValue(string) on parent Field class, e.g.: 
> {code}
> Field b = new BinaryField(); 
> b.setValue( ..byte[] value.. );
> {code}
> One idea is to use generics:
> {code}
> Field<String> s = new StringField();
> {code}
