The tree structure is not an object itself, but is \ emergent from the linkages you create between nodes. This class \ provides the methods for making linkages that can be used to build up a \ tree, while preventing you from ever making any kinds of linkages which \ are not allowed in a tree (such as having a node be its own mother or \ ancestor, or having a node have two mothers). platforms darwin checksums md5 233f5b2c0cfaa891d2e8cf87aaea3b68
