Description

       This  is  the  base object that can be casted to other objects that to describe a DNS message, how it was
       captured or generated.  Objects can be chained together, for example a DNS message is created ontop of  a
       packet.

   Attributes
       obj_type
              The enum of the object type.

       obj_prev
              The previous object in the object chain.

   FunctionsObject:type()
              Return the textual type of the object.

       Object:prev()
              Return the previous object.

       Object:cast()
              Cast the object to the underlining object module and return it.

       Object:cast_to(obj_type)
              Cast  the  object  to  the specified object module and return it.  Returns nil if the object chain
              doesn't contained the specified object type.

       Object:uncast()
              Cast the object to the generic object module and return it.
