Comment:

 This ticket covers logging to two destinations: to a file and to a
 terminal.  Output to syslog has been deferred to ticket #976.

 The ticket was branched from #899 at
 862e13c5c852b8ea55c1b53a67803105d473a342.

 Broadly speaking, the changes have been:
  * Create a !LoggerManager class (and an associated implementation class)
 to control logging initialization and the configuration of loggers.  This
 has meant moving initialization out of the Logger and !LoggerImpl classes.
  * Add code to create a file appender and a console appender (and
 associated unit tests)
  * Reorganise the sh-based tests around the (renamed) logger_example
 program.  Each shell script now tests one aspect of the logger.
