-// .NAME vtkPointAccumulator - Container class that manages appending data arrays of points.
-// .SECTION Description
-//
-// The template types are T_CPP for the c++ data type and T_VTK for
-// the VTK data type. Eg: if T_CCP==double the T_VTK must be
-// vtkDoubleArray. The main difference between the way this
-// works and if you were to do the same thing with a data array is
-// that here the memory grows by exactly what is needed, and
-// in VTK data arrays the memory will grow by at least twice
-// what is requested.
