// .NAME vtkImageAppendComponents - Collects components from two inputs into
// one output.
// .SECTION Description
// vtkImageAppendComponents takes the components from two inputs and merges
// them into one output. If Input1 has M compoennts, and Input2 has N 
// components, the output will have M+N compoennts with input1
// components comming first.
