/**
* This is a test to benchmark TaskScheduler execution.
*
* This test executes 1,000,000 cycles of a task with empty callback method
* Compiled with different options, you can assess the impact of each on the size of the Task object
* and the execution overhead of the main execution pass route.
*
* Sample execution times (in milliseconds per 1M iterations) are provided below.
* The test board is Arduino UNO 16MHz processor.
*
