Summary:                    Inconsistency in naming multi-component arrays in
Exodus files
Description: 
When writing out array data with more than one component using one of VTK's
native formats, the array names are stored as strings.
If vtkArrays are written out using the Exodus file format (vtkExodusIIWriter),
the nomenclature is slightly different:

 * Arrays with two components are stored as
    <array name>_R
    <array name>_Z
 * Arrays with three components are stores as
    <array name>X
    <array name>Y
    <array name>Z

While it is not clear to me why the extensions are "R" and "Z" in the
two-component case, it is the inconsistency in the underscore handling that
makes those files harder to deal with. Even when viewing such files in ParaView,
two-dimensional arrays would be displayed as "v_", three-dimensional ones as
"v".
