/** class for collecting anchored objects

    for #i28701#
    Anchored objects can be inserted and deleted. The entries can be directly
    accessed via index.
    An anchored object is inserted sorted. The sort criteria are:
    - anchor type
      - order 1: to-page, 2: to-fly, 3: to-paragraph|to-character|as-character
    - anchor node
    - wrapping style (inclusive layer)
      - order 1: wrapping style != css::text::WrapTextMode_THROUGH and not in hell layer,
        2: wrapping style = css::text::WrapTextMode_THROUGH or in hell layer
    - wrapping style influence
      - order 1: NONE_SUCCESSIVE_POSITIONED, 2: NONE_CONCURRENT_POSITIONED
    - again anchor type
      - order 1: to-paragraph, 2: to-character, 3: as-character
    - anchor node position
    - internal anchor order number
    If one of the sort criteria attributes of an anchored object changes,
    the sorting has to be updated - use method <Update(..)>
