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.
