Implement AttributeType=Matrix

I would like to see the Matrix type implemented so that ParaView can open the files. A clear Example on how to use the Matrix AttributeMatrix. For example I have a triangular surface mesh where each triangle has a (2x1) matrix of values so that each triangle has 2 values. Currently we have to setup a hyper slab for the data array and end up with 2 data items.

   <Attribute Name="SurfaceMeshFaceLabels (Feature 0)" AttributeType="Scalar" Center="Cell">
     <DataItem ItemType="HyperSlab" Dimensions="757136 1" Type="HyperSlab" Name="SurfaceMeshFaceLabels (Feature 0)" >
       <DataItem Dimensions="3 2" Format="XML" >
         0        0
         1        1
         757136 1 </DataItem>
       <DataItem Format="HDF" Dimensions="757136 2" NumberType="Int" Precision="4" >
       Matrix_XDMF_Test.dream3d:/DataContainers/SurfaceDataContainer/FaceData/SurfaceMeshFaceLabels
       </DataItem>
     </DataItem>
   </Attribute>

   <Attribute Name="SurfaceMeshFaceLabels (Feature 1)" AttributeType="Scalar" Center="Cell">
     <DataItem ItemType="HyperSlab" Dimensions="757136 1" Type="HyperSlab" Name="SurfaceMeshFaceLabels (Feature 1)" >
       <DataItem Dimensions="3 2" Format="XML" >
         0        1
         1        1
         757136 1 </DataItem>
       <DataItem Format="HDF" Dimensions="757136 2" NumberType="Int" Precision="4" >
       Matrix_XDMF_Test.dream3d:/DataContainers/SurfaceDataContainer/FaceData/SurfaceMeshFaceLabels
       </DataItem>
     </DataItem>
   </Attribute>

I would rather do something like this:

   <Attribute Center="Cell" Name="Phases_Matrix" Type="Matrix">
     <DataItem Dimensions="2 1" Format="XML" >2 1</DataItem>
     <DataItem DataType="Int" Dimensions="757136 2" Format="HDF" Precision="4">
       Matrix_XDMF_Test.dream3d:/DataContainers/SurfaceDataContainer/FaceData/SurfaceMeshFaceLabels
     </DataItem>
   </Attribute>

Or something like that.

1DCoRectMesh

I will like to have also something like 1DCORECTMesh, for the moment I Use a 2DCORECTMesh with only 1 point in the second direction. But cant be used with cell data (paraview crash). So I use only point data.
