Helpful extensions that make it easier to manipulate JSON values.
Nulls propagate through calls so for example, given a JSON object like { 'typeInfo': { 'bar' : 2 } }, you could just write obj.Get("typeInfo").Get("bar").AsInteger() to get the value 2. Given a JSON object like { 'baz': 2 }, you could write obj.Get("typeInfo").Get("bar").AsInteger() to get the value null.
