[vtkusers] vtkContourFilter and SelectInputScalars(String)

[Randall Hand]

You have to find out the "port ID's" for the input data (only way I've found 
so far is digging through source), and do things like this:

filter->SetInputArrayToProcess(id, 0, 0, 0, "fieldname");

Look in the constructor for the class.. Seems that the ContourFilter only 
supports 1 port: port 0 is the Scalar Field.
I went through this for the vtkGlyph3D class last week, it supports 4 ports:
port - Data
0 Scalars to use for scaling
1 Vector for aligning glyphs
2 Normals
3 Scalars to use for color
