%% Syntax:
% Filtered,Filter] = periodicMedianFilter(RawData, HumPeriod)
% Filtered,Filter] = periodicMedianFilter(RawData, HumPeriod, Window)
% Filtered,Filter] = periodicMedianFilter(RawData, HumPeriod, Window, Plot, PowerLineHum)
%
%% mandatory parameters:
% RawData = series of data with power line hum
% Humperiod = the (whole) number of samples over which the hum repeats (e.g. 1000/50=20 if sample freq=1000)
%
%% optional parameters
% Window [optional] = the number of periods on the sliding window (default 50; 0=entire range) % Plot [optional] default 0=none; 1=make a comparison plot and FFT; 2=also plot the filter
