// .NAME vtkSMOrderedPropertyIterator - iterates over the properties of a proxy
// .SECTION Description
// vtkSMOrderedPropertyIterator is used to iterate over the properties of a
// proxy. The properties of the root proxies as well as sub-proxies are
// included in the iteration. For sub-proxies, only exposed properties are
// iterated over. vtkSMOrderedPropertyIterator iterates over properties in
// the order they appear in the xml or in the order they were added. This
// is possible because vtkSMProxy keeps track of the order in which properties
// were added or exposed in a PropertyNamesInOrder vector.
