% DetectSaccade360IVTFile.m
%
% This function uses a simple speed threshold as in I-VT to detect saccades. 
% The result is stored as a attribute in the output file with values of 
% '{unassigned, saccade}'
%
% input:
%   arffFile     - file to label
%   outputfile   - ARFF file to store detected saccades
%   outputAtt    - attribute that holds detected saccades in the output ARFF file
%   typeOfMotion - 1 -> eye FOV, 2 -> eye+head
%   velThreshold - velocity threshold for I-Vt
