 ===== Motivation =====
-Both heart beat onsets (R wave time points) as well as sliding beats-per-minute, (BPM) are already interesting measures, both most publications refer to summarizes measures when GCR data reported. One of the most common of these is heart-rate variability (HRV). This function computes the power spectral contribution of frequencies in two specified ranges.

+**Note: if the function (heartbeats) is called twice with plotting enabled, the result of the overview of the first call will be re-positioned so that it can be easily used as input to the second pass.**
