Enumerates all values in the Trie in lexicographic key order. The 
Key property is set for each enumerated value.
If you picture the Trie as a tree (and have all child nodes ordered lexicographically), the lexicographic traversal
of the trie is the pre-order traversal of the tree (only counting nodes with a value).
