Add an "auto" property class

[bladeoflight16]

C# has some nice syntax that allows you to avoid explicitly creating an extra, underlying instance variable to store the value when your variable doesn't have any extra processing:

public String MyString { get; set; }

I believe it would be possible to provide an out of the box implementation of this by extending your Property class. I imagine it would look something like this:

public class AutoProperty<T> extends Property<T> {
    private T value;
    public AutoProperty() {
        super(() -> this.value, newValue -> this.value = newValue);
    }
}

Then it would be used like this:

public class MyClass {
     public Property<String> myString = AutoProperty<String>();
}

(I haven't fully flushed out the implications of this code. It's just an example implementation to start off with.)
