Some notes on the MySQL adaptor implementation:

* Currently this is designed to work with MySQL v3.22 databases.
  3.23+ support (transactions, etc.) will be coming soon.

* The MySQL "time" column type is converted to NSCalendarDate in an
  interesting way.  Since the "time" type is actually a time interval
  (the hours can be greater than 23, or even negative), it is stored
  as an interval relative to the "reference date" in the NSDate class
  cluster.  It should be created using code like

	date = [NSCalendarDate dateWithTimeIntervalSinceReferenceDate:
				(int) interval];

  If you try to create it using the dateWithString, and specifying a
  format string with just the hour, minute, and second fields, it will
  likely fail due to strange conversions within NSDate.
