Replacing usage of ShallowNodeIterator to loop throw node children by
explicit calls to Node.getFirstChild()/ Node.getNextSibling()) with
comments when the node children list is modified while iterating
through it.
It avoids creation of ShallowNodeIterator objects and eliminates the
need to have ShallowNodeIterator class.
