*
* 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.
