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

typedef CopyConstness<NodeT, typename NodeT::ChildNodeType>::Type ChildT |

typedef IterTraits<typename PrevIterT::NonConstNodeType, PrevIterT>::template NodeConverter<_NodeT>::Type IterT |
The type of iterator stored in this list item (e.g., InternalNode<...>::ValueOnCIter)
typedef IterTraits<NCNodeT, IterT> ITraits |
typedef CopyConstness<NCNodeT, typename NCNodeT::ChildNodeType>::Type NCChildT |
NodeT's child node type with const qualifiers removed.
typedef IterT::NonConstNodeType NCNodeT |
The type of the node with const qualifiers removed ("Non-Const")
typedef IterT::NonConstValueType NCValueT |
The type of value (with const qualifiers removed) to which the iterator points.
typedef IterT::NodeType NodeT |
The type of node (const or non-const) over which IterT iterates (e.g., const RootNode<...>)
typedef PrevItemT::IterT PrevIterT |
The type of iterator stored in the previous list item.
