Add new util.address.ObjectOf

[thekid]

This class can replace util.address.CreationOf which only works in conjunction with the WithCreation trait. The ObjectOf definition instead creates instances of the given type (without invoking their constructor) and directly sets member variables.

Refactoring is easy:

-use util\address\CreationOf;
+use util\address\ObjectOf; 

 $address= new XmlString('<book>Name</book>');
-$book= $address->next(new CreationOf(Book::with(), [
+$book= $address->next(new ObjectOf(Book::class, [
   '.' => function($iteration) { $this->name= $iteration->next(); }
 ]));

Also, the util.address.WithCreation trait can be removed from the Book class.
