[vtkusers] How to name components

[Sanjay Govindjee]

I am writing point data to a file and would like to be able to 
name/label the compoents:
So I have something like:

<PointData>
<DataArray type="Float64" Name="History" NumberOfComponents=" 4" 
format="ascii">
.....lots of numbers....
</DataArray>
</PointData>

I would like to be able to set the names of the components so that
say component 1 is labeled xx, compoent 2 is labeled yy, etc.
