		std::set< int > &	originalNodes,
		std::map< int, std::map< int, int > > &	nodeDomains,
		std::map< int, std::map< long, int > > &	nodeQuadDomains
	)

Create a volume (prism or hexahedron) by duplication of a face.

Designed for use in creation of flat elements separating volume domains. A face separating two domains is shared by two volume cells. All the nodes are already created (for the two faces). Each original Node is associated to corresponding nodes in the domains. Some nodes may be duplicated for more than two domains, when domain separations intersect. In that case, even some of the nodes to use for the original face may be changed.

Parameters

vtkVolId,:	vtk id of a volume containing the face, to get an orientation for the face.
domain1,:	domain of the original face
domain2,:	domain of the duplicated face
originalNodes,:	the vtk node ids of the original face
nodeDomains,:	map(original id –> map(domain –> duplicated node id))

Returns: ok if success.

	)

Get the neighbors of a cell.

Only the neighbors having the dimension of the cell are taken into account (neighbors of a volume are the volumes sharing a face with this volume, neighbors of a face are the faces sharing an edge with this face...).

Parameters

neighborsVtkIds	vector of neighbors vtk id's to fill (reserve enough space).
downIds	downward id's of cells of dimension n-1, to fill (reserve enough space).
downTypes	vtk types of cells of dimension n-1, to fill (reserve enough space).
vtkId	the vtk id of the cell

Returns: number of neighbors
