This PR is not at all intended to be merged currently, just for visibility in case somebody finds this useful..

Currently "-b" (backtrace) controls over what time window (backwards from
now) the psd is computed and "-u" (update time) controls after what
interval a new psd is computed. Old psds continually get more
transparent and weaker in linewidth (== kind of fade out). Lots of
values hard coded right now (frequ limits, number of old psds to keep,
etc).

Oh, right, command line parameters.. sorry, too long ago, no idea. You'll just have to try some values.

I think this would really only be useful to debug certain electrical problems when setting up a station (e.g. getting rid of 50Hz hum, ...), i.e. when you have some sharp changes in the psd.

For a monitor plot maybe some of the new PPSD plots could maybe be plugged into seedlink plotter, see obspy/obspy#1327. Those would be more consistent with the time axis of the normal seedlink plotter..
