[vtkusers] vtkArrayCalculator function definition syntax????

[W.T. Bridgman]

I want to do a cross product of two vector datasets.

I  can't find any documentation (both the vtk list & Google) on  
vtkArrayCalculator or vtkFunctionParser to implement this.

How would I code the SetFunction for this?  Does the parser recognize  
vector components?

E[3]=V[2]*B[1]-V[1]*B[2], etc.

Thanks,
Tom
