// .NAME vtkSMPProgressObserver - Progress observer that is thread safe
// .SECTION Description
// vtkSMPProgressObserver is designed to handle progress events coming
// from an algorithm in a thread safe way. It does this by using
// thread local objects that it updates. To receive the progress
// information, one has to listen to the local observer in the same
// thread. Since the execution will be somewhat load balanced,
// it may be enough to do this only on the main thread.
