[vtkusers] Build Local vtk Classes

[Yi-Yu Chou]

Dear vtk usrs,

I can successfully build my own vtk classes by following the
instructions in ${VTKSRC}/Examples/Build/vtkMy under window/linux with
vtk4.2 and python . However, I was wondering if it's possible to build
a "totally independent" local class.
Ex: I would like to build a new class (module) under local folder A,
and use it under folder B, C,......without compilimg again.
(Currently I need to re-compile everything under each folder.)

Thanks for the help !!!!!
