/**
 * 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.
