General:
+* Introduce to_parent() (replaces operator!() as of the proposal), to_begin() and to_end()
+ cursor members that work on "*this" cursor instead of returning a new object.
* Should const_cursor have cbegin(), cend() and cparent() members?
* Implement "flat" (sequential *order representation) trees (cf. Knuth, Fundamental Algorithms,
pp. 348--351). Those should be especially useful for automated testing of "real" (binary,
