Popular ECG R peak detectors written in python

A collection of 7 ECG heartbeat detection algorithms implemented in Python. Developed in conjunction with a new ECG database: http://researchdata.gla.ac.uk/716/. This repository also contains a testing class for the MITDB and the new University of Glasgow database. In addition the module hrv provides tools to analyse heartrate variability. This release removes some unnecessary packages references such as biosppy and pathlib. Otherwise it's identical to the previous release. After half a year no bugs have been reported I bump up the version number to 1.0.0
