// Testing the MetricOutputManager object.
//
// Verbosity levels are
//  NO_STATUS,
//  BASIC_STATUS,
//  DETAILED_STATUS,
//  VERBOSE_DETAILED_STATUS
//  NUM_STATUS_OUTPUT_LEVELS
//
//  This test can only really be verified by reading the output.
//  So we are testing that MetricOutputManager doesn't crash.
