/**
    This is example 5 rewritten with dynamic binding of callback methods
    - 1 second timeout is set for the main calculation task
    - LTS is used to address task-specific sensor class object
    - WDT is used to set the Task ID and use that for identifying the tasks (debug)

    Original description:
    ====================
      This test emulates querying 1 to 10 sensors once every 10 seconds, each could respond with a different delay
      (ultrasonic sensors for instance) and printing a max value of them when all have reported their values.
      The overall timeout of 1 second is setup as well.
      An error message needs to be printed if a timeout occurred instead of a distance value.

      Task and SuperSensor objects are dynamically created and destroyed as needed every 10 seconds

       This sketch uses a FreeMemory library: https://github.com/McNeight/MemoryFree
	   FreeMemory for ARM32 boards is based on: http://www.stm32duino.com/viewtopic.php?f=18&t=2065
