based on some type of generic 'TreeItem' class.  I'm not sure that a 
TreeItem can always be represented as a string.

Each node can be identified by a unique ID (which can be an integer, 
which can be then converted as a string).

Thus, besides all IDs, you need to persist all parent-child relationship 
- which I think is about it.
