[vtkusers] Help for using of cone source

[David E DeMarle]

For the first question, about merging, I'ld try:
  vtkConeSource<vtkTransformFilter[0-12]>vtkAppendPolyData
Where < represents a branch in the pipeline and > represents a merge.

For the second question, about registration, I have no hints to give.
