Smoothing filters continue to be of interest to scipy users. I wrote a 
regularization-based smoothing method a few years ago:

https://github.com/jjstickel/scikit-datasmooth/
https://pypi.python.org/pypi/scikits.datasmooth/0.61

and suggested then that several smoothing methods be co-located inside 
or outside scipy but did not get enough traction to make this happen. 
Any further interest in this now? It seems that a subbranch of 
scipy.signal would be logical (e.g. scipy.signal.smoothing). Or perhaps 
a single function interface to several smoothing methods (spline, S-G, 
wavelet, regularization, others).

I have limited time, but I would be willing to work on a pull request or 
such with some coaching (it would be my first).

Thanks,
Jonathan
