[vtkusers] Adopt an example

[Darshan Pai]

VectorDot example .

I don't think the output is wrong . The Values should be -1 . This is
because the vtkVectorDot initial scalar range is from -1 to 1 . And the
class does not generate the dot product values but rather generate scalar
values based off dot product . Since the example generates only one value
that is 1, it is mapped to the lower range of scalar .

If you set the scalar range of vtkVectorDot to say (3,6) , the output is 3,
which should be correct right ?
