    I treid to clean up Whitehead tower a bit:

    I rewrote and expanded the Idea/Definition part.

    Then I moved David Roberts' material that was there to the appropriate section at the new Whitehead tower in an (infinity,1)-topos. (There I tried to add some introductory remarks to it but will try to further highlight David's results here in a moment).

    At Whitehead tower I left just a new section that says that there is a notion of Whitehead towers in more general contexts with a pointer to Whitehead tower in an (infinity,1)-topos

    I have added at Whitehead tower in the Examples-section Whitehead tower of the orthogonal group a big diagram giving more details on the statement that was indicated there earlier: horizontally running the Postnikov tower, vertically the Whitehead tower, and diagonally the homotopy groups.
