/**
* Created by Peter De Jonckheere on 17/01/2018.
* <p>
* The strategy which uses the significant motion sensor provided by Android in conjunction
* with the step counter sensor to determine movement and sedentary behaviour. This method is
* as accurate as the accelerometer method but requires less power as the reporting mode of
* both sensors used in this method is not as persistent as streaming. Uses the step counter in
* addition to this class as a time period for which the movement lasted was required to be
* determined.
