/* MimeContainer is the class for the objects representing all MIME 
   types which can contain other MIME objects within them.  In addition 
   to the methods inherited from MimeObject, it provides one method:

   int add_child (MimeObject *parent, MimeObject *child)

     Given a parent (a subclass of MimeContainer) this method adds the
     child (any MIME object) to the parent's list of children.

     The MimeContainer `finalize' method will finalize the children as well.
