Detailed Description

A simple feature calculation that computes the centroid in time of a given chunk.

This might be useful in seeing where a chunk is localized in time (e.g. a stationary sinusoid will have a TimeCentroid of .5, but a drum hit with a fast decay will have a TimeCentroid closer to 0), or to test an OnsetDetector.
