 * 
 * Simple class for manipulating 16-byte keys.
 * This class simply encapsulates the storage and (lexical) comparison
 * of 16-byte binary keys.  Generally, _Tt_db_key is the class to
 * use to hold and manipulate keys; only code which depends on the
 * lexical ordering of keys (which should only be the inspect-and-
 * repair tools) should use this class.
