47/// IterTraits provides the following for iterators of the standard types,
48/// i.e., for {Child,Value}{On,Off,All}{Iter,CIter}:
49/// - a NodeConverter template to convert an iterator for one type of node
50/// to an iterator of the same type for another type of node; for example,
51/// IterTraits<RootNode, RootNode::ValueOnIter>::NodeConverter<LeafNode>::Type
52/// is synonymous with LeafNode::ValueOnIter.
53/// - a begin(node) function that returns a begin iterator for a node of arbitrary type;
54/// for example, IterTraits<LeafNode, LeafNode::ValueOnIter>::begin(leaf) returns
55/// leaf.beginValueOn()
56/// - a getChild() function that returns a pointer to the child node to which the iterator
57/// is currently pointing (always null if the iterator is a Value iterator)

202/// @brief An IterListItem is an element of a compile-time linked list of iterators
203/// to nodes of different types.
204///
205/// The list is constructed by traversing the template hierarchy of a Tree in reverse order,
206/// so typically the elements will be a LeafNode iterator of some type (e.g., ValueOnCIter),
207/// followed by one or more InternalNode iterators of the same type, followed by a RootNode
208/// iterator of the same type.
209///
210/// The length of the list is fixed at compile time, and because it is implemented using
211/// nested, templated classes, much of the list traversal logic can be optimized away.
