4.3 Power

A custom policy function is added to stepper_motor.c to count the amount of time spent idling when the CPU is not performing any actions. This is then reported to the user as a measurement of the application total CPU usage. The stepper_motor.syscfg SysConfig file power module directly refers to this custom policy function so that the function is used. Consider this feature for test and evaluation only.
