/**
 * Marks an interface as interface to json type object. This way user may hold JSON object in
 * form of statically typed Java interface. The interface provides methods for reading properties
 * (here called fields, because we imply there are "types" in JSON) and for accessing subtypes.
 * <p/>
 * In this design casting to subtypes means getting a different object of the subtype interface.
 * For a type interface, a set of subtypes is defined by its methods
 * with {@link JsonSubtypeCasting} annotation. These methods provide access to subtype objects.
