Changes in this pull request:

• For the async findMax (the default) all instances exit InitialRamp at the same time. They will exit initialRamp when half or more of the instances fail an interval.
• For the sync findMax all instances exit InitialRamp at the same time. They will exit initialRamp when half or more of the instances fail an interval.
• Cleaned up the output so that messages for instances that are in the same phase and number of uses are combined. This works for async as well as sync.
• Adjusted the QoS requirements:
  • The mix tolerance is now 20% for operations which make up less than 5% of the mix
  • The Failure percent is now 0.5% rather than 0.1%
