NAME

       domain_indirect - a named part of a finite element mesh

DESCRIPTION

       The  domain_indirect  class  defines a container for a part of a finite element mesh.  This describes the
       connectivity of edges or faces.  This class is usefull for boundary condition setting.

IMPLEMENTATION NOTE

       The domain class is splitted into two parts.  The first one is the domain_indirect class,  that  contains
       the  main  renumbering features: it acts as a indirect on a geo class(see geo(2)).  The second one is the
       domain class, that simply contains two smart_pointers: one on a domain_indirect and the second on the geo
       where renumbering is acting.  Thus, the domain class develops a  complete  geo-like  interface,  via  the
       geo_abstract_rep  pure  virtual class derivation, and can be used by the space class (see space(2)).  The
       split between domain_indirect and domain  is  necessary,  because  the  geo  class  contains  a  list  of
       domain_indirect.   It  cannot  contains  a list of domain classes, that refers to the geo class itself: a
       loop in reference counting leads to a blocking situation in the automatic deallocation.
