create objects late from non-owned classes

 Object::Lazy implements lazy evaluation and can create lazy objects from
 every class.
 .
 Creates a dummy object including a subroutine which knows how to build the
 real object.
 .
 Later, if a method of the object is called, the real object will be built.
 .
 Inherited methods from UNIVERSAL.pm are implemented and so overwritten. This
 are isa, DOES, can and VERSION.
