Allow customizing of object labels

[orionll]

Proposal

Can we add methods like:

// Set the same label for all objects of the given class
public LJV setClassLabel(Class<?> cz, String label);

// Set a label for an individual object of the given class
public <T> LJV setObjectLabelProvider(Class<T> cz, ObjectLabelProvider<T> labelProvider);

// Set a label for individual objects of the given class (only if it's a specific field)
public <T> LJV setObjectLabelProvider(Field field, Class<T> cz, ObjectLabelProvider<T> labelProvider);

@FunctionalInterface
public interface ObjectLabelProvider<T> {
    String getLabel(T obj);
}

Examples

var p = new SimpleImmutableEntry(1, 2);
browse(new LJV().setClassLabel(SimpleImmutableEntry.class, "Entry"), p);

var list = new ArrayList<>();
list.add(1);
list.add(2);
browse(new LJV()
        .setTreatAsPrimitive(Integer.class)
        .setObjectLabelProvider(ArrayList.class, lst -> lst.getClass().getName() + "@" + System.identityHashCode(lst)),
        list);

var string = "hello";
browse(new LJV()
        .setObjectLabelProvider(String.class, str -> str)
        .setObjectLabelProvider(byte.class, b -> "0x" + Integer.toHexString(Byte.toUnsignedInt(b))),
        string);

Issues

• Primitives. Should we add IntLabelProvider, LongLabelProvider, ByteLabelProvider or use setObjectLabelProvider(int.class, (Integer x) -> )?
• Inheritance. Should setClassLabel(List.class, ...) work only for List or ArrayList, LinkedList and other subclasses?
