[vtkusers] What does VTK_*_EXPORT do?

[Marcus D. Hanwell]

And more recently, GCC visibility in newer versions of GCC. It decorates
class declarations with the correct attributes to be exported (and on
Windows imported) in shared libraries (DLLs, .so, .dylib etc). Internal
classes do not need it, but anything that can be called as part of our API
should have this macro before it.
