Description:


implements the tabs-view component of a noteBook.
May also be used on its own (without a surrounding noteBook).

The functionality is basically the same as provided by a
PopUpList or SelectionInListView, in that a valueHolder
gets a value assigned corresponding to the selected tab
from a list of possible tabs.
