cluster population average of individual networks
perform measurements after reproduction
convert edgelist or linklist to pajek format
optional plotting, plotting function, move measurement to measure.jl in order to enable control over frequency of measurement

switch to using files rather than named pipes due to slowdown induced by @spawn
plot errorbars with measures if y_name+std is available as a column in the dataframe
