Check if node has been visited about tree HOT 2 OPEN

As the Readme says, the data is read-only – you can completely replace the data of the whole tree, but no nodes or nodes’ properties individually.

Which means this has to be done by the client (i.e. your code). However, maybe you don’t even need to do that, as using $tree->getNodes(), you can iterate over all nodes, so that you can be sure that your code “sees” each node exactly once when iterating.

Alternatively, if for some reason the visited property needs to be in the nodes, you can still subclass the Node class and make that possible.
