class Webgen::ItemTracker::TemplateChain

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)
