 * When logging messages to the debug log each message has a debug level
 * based on this enum.  The logger has a filter level based on this enum
 * also.  Messages of lower priority than the current debug level will
 * not be logged.
 * 
 * Note that 99% of the time the "current" debug level is determined by
 * the current TaskContext.  The preferred way to log messages is through 
 * the TaskContext or through an OperationResult.  Ultimately a filter
 * is used to determine what should go in the log.
