This CL implements Welford's algorithm for a numerically stable computation of the variance. This implementation is plugged in SamplesStatsCounter class (adapter pattern). A 'NumericalStability' unit test has been added, whose previous implementation of SamplesStatsCounter failed to pass. Follow-up CLs will factorize more occurences of duplicated and misbehaved computations.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
Authoritative list of directories that contain the native API header files.
