% DetectFixations360IDTFile.m
%
% This function detects fixations based on the I-DT algorithm. 
% The result is stored as a new attribute in the output file with values of 
% '{unassigned, fixation}'
%
% input:
%   arffFile        - file to label
%   outputfile      - ARFF file to store detected fixations
%   outputAtt       - attribute that holds detected fixations in the output ARFF file
%   typeOfMotion    - 1 -> eye FOV, 2 -> eye+head
%   dispThres       - dispersion threshold in degrees
%   windowDur       - window duration in us
