Wyzerowanie (czyszczenie) witryny sharepoint

Czyli... coś czego... niemal nigdy nie powinno się robić, jednak moja wyobraźnia jest na tyle pojęta, że... jednak jestem w stanie sobie wyobrazić syt. w której trzeba programistycznie wyczyścić całą witrynę sharepoint. Można to zrobić za pomocą przedstawionej poniżej metody, którą można podpiąć pod kod deaktywujący feature.

Uwaga: ta metoda jest niczym "broń atomowa" dla witryny sharepoint, więc jej ewentualne użycie powinno być wcześniej 10-krotnie przemyślane.
