/**
 * 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.
 *
