@brief Lookup a node by name.

Looks up a node with the given name and returns it. Anchor nodes (nodes whose name starts with ‘!’) can be looked up by name, excluding the leading ‘!’. Standard nodes can also be looked up by name. Non-anchor nodes are assigned a unique name by suffixing them with #${unique}. They can be looked up if you know the unique name.
