# This class is used to track the template chain for a node.
#
# Note that only nodes that support the #template_chain method can be used (so all page,
# template and custom webgen nodes are okay).
#
# The item for this tracker is the node whose template chain should be tracked, i.e. add an item
# like this:
#
# website.ext.item_tracker.add(some_node, :template_chain, other_node)
