Median filter C++ code sample

This routine is much useful for detecting spikes on a variable baseline but performs superiorly to the low-pass filtered derivative when spikes frequency content is close to that of the baseline. The principle of this algorithm is comparable to a running-average, except that instead of computing an average, we estimate the median. This approach is more computer-intensive but works quite well on real data.
