// A utility class for block-flow layout which given the first child and a
// break token will iterate through unfinished children.
//
// NextChild() is used to iterate through the children. This will be done in
// node order. If there are child break tokens, though, their nodes will be
// processed first, in break token order (which may or may not be the same as
// node order). When we're through those, we proceed to the next sibling node of
// that of the last break token - unless we have already seen and started all
// children (in which case the parent break token will be marked as such;
// |HasSeenAllChildren()| will return true).
//
// This class does not handle modifications to its arguments after it has been
// constructed.
