Inheritance / Polymorphism

A highly request feature is polymorphism. Mostly for use in ListAdapters, but a lot of other scenarios exists. We need support for the following: - Abstract RealmObject classes - Query support Example ``` public abstract Animal extends RealmObject { private String name; } public class Dog extends Animal { private boolean willPlayCatch; } public class Spider extends Animal { private boolean isScary; } // Following should be possible RealmResults<Animal> animals = realm.where(Animal.class).equalsTo("name","Foo").findAll(); String name = animals.get(0).getName(); RealmResults<Dog> dogs = realm.where(Dog.class).equalsTo("name","Foo").and().equalsTo("willPlayCatch", true).findAll(); String name = dogs.get(0).getName(); ```
