\note When constructing Circulators from iterators, make sure you don't create
a circulator of an deleted element(e.g. FaceVertexiter of a deleted Face), as
this will lead to unpredictable behaviour. Using skipping iterators for iterating over
the elements and creating circulators from them is safe as they don't contain
deleted elements.
