Added the Baevsky Stress index calculation to measures with the corresponding building blocks of the main formula:
si = AMo / (2 VR Mo)
where
R-R interval - the time delay between consecutive heartbeats (assumed to be the inverse value of the bpm)
Mo - mode - most frequent R-R interval value
AMo - mode amplitude - % of the intervals corresponding to Mode
VR - variational range - the difference between min and max R-R intervals
