752	Base Classes for Trees	wiz	Adrian Holovaty	"Base classes, what could efficiently handle large tree-like structures.

  * Recursive handling (delete, move, rebuild, and so)
  * Querying for children in some ways, with filters
    * Nearest
    * By path
    * Level[s] slice
    * Parents
  * Node data types handling. Mapping to other classes.

I think it would be 2 classes: one for handling tree structure and one base class for node items."	enhancement	closed	Metasystem		normal	wontfix			Unreviewed	0	0	0	0	0	0
