Support for excluding fields

[tungp99]

In my needs, the POJO has some property which link directly to another POJO. From .net background, I believe it's called lazy-loading prop. My workaround is available so you can consider this as suggestion.

class Person {
...
}

class Teacher {
@Id
private int personId
...
// this prop is null in json file, I would love to have it deleted
public Person person;
}
