Function to get the stance phase from vertical GRF.

Uses C. Maiwald, T. Sterzing, T. a. Mayer, and T. L. Milani, Detecting foot-to-ground contact from kinematic data in running, Footwear Sci., vol. 1, no. 2, pp. 111-118, Jun. 2009. => "True touch down and take off events were initially determined from force plate data by applying a threshold of 10N for touch down and 5 N for take off (O'Connor et al. 2007) to the vertical GRF data."

Warning: The algorithm is not perfect up to now. Sometime there are errors in the result.

Parameters

verticalGRF

Double array: Vertical ground reaction force in N

Return values

standing	Double array: 0: no standing; 1: standing (length of verticalGRF)
idxHSs	Double array: Indices of heel strikes (length is number of heel strikes)
idxTOs	Double array: Indices of toe offs (length is number of toe offs)
