My headers don't seem to follow this rule. I checked the headers for 
vtkFloatArray and vtkCharArray (VTK 4.4.2). According to the above, 
both should supply the SetArray method to the Tcl interface. But this 
command is only available for vtkCharArray in my build (on OSX 10.3). 
Is there something else going on here?
