//! Class to support data side Sets.
/*!
	XdmfSet is a Class that handles sets of nodes,cells,faces, and edges
	on an XdmfGrid. They may be centered on the Node, Edge,
	Face, Cell. An XdmfSet can have from 1 to 3 DataItems. The last DataItem
    is always the "Ids" or the indexes into Nodes, Cells, etc. If SetType is
    "Face" or "Edge", the First DataItem defines the CellIds. If SetType is
    "Edge" second DataItem defines FaceIds

    \verbatim
    XML Element Name : Set
    XML Set : Name
    XML Set : SetType = Node* | Cell | Grid | Face | Edge
    XML Set : Ghost = #  Ghost node/cell owner if > 0 ; usually 1
    XML Set : FaceOrder = "0 1 ..." Mapping to Default Order
    XML Set : EdgeOrder = "0 1 ..." Mapping to Default Order

    Example :
        <Set Name="Ids" SetType="Node" SetLength="4">
            <DataItem Format="XML" Dimensions="4" >
                1 2 3 4
            </DataItem>
            <Attribute Name="Force" Center="Node">
                <DataItem Format="XML" Dimensions="4" >
                    100.0 110.0 100.0 200.0
                </DataItem>
            </Attribute>
        </Set>

        Or for Ghosr Cells

        <Set Name="Proc3GhostCells" SetType="Cell" SetLength="2" Ghost="3">
            <DataItem Format="XML" Dimensions="2" >
                3 40
            </DataItem>
        </Set>
