    % Load all of the .mat files in the specified data directory. These
    % were the original files of data captured. There were some issues with
    % the data, namely it was not modified to have the x,y,z axes fixed,
    % and the biggest problem is that the order of the data is suspect. I
    % did some fixing of the capture later, so I am not certain of the
    % ordering of the IMU data. Hand is always first, then the other items
    % are unclear.
