%> @details This is the skeleton file for processing data data from a foot
%> mounted inertial measurement unit (IMU). The data is processed using a
%> Kalman filter based zero-velocity aided inertial navigation system. The
%> processing is done in the following order.
%>
%> \li The IMU data and the settings controlling the Kalman filter is loaded.
%> \li The zero-velocity detector process all the IMU data.
%> \li The filter algorithm is processed.
%> \li The in data and results of the processing is plotted.
