/* "Rotating trees" (Armin Rigo)
 *
 * Google "splay trees" for the general idea.
 *
 * It's a dict-like data structure that works best when accesses are not
 * random, but follow a strong pattern.  The one implemented here is for
 * access patterns where the same small set of keys is looked up over
 * and over again, and this set of keys evolves slowly over time.
