6176	rolling_mean not as flexible as mean	s.d.c.west@…	Eric Niebler	"The mean_impl struct has a SumFeature template parameters that allows it to be used to calculate the mean of weights and the mean of variates in addition to the standard mean.

There is no corresponding template parameter for rolling_mean_impl, so it is less flexible. If this were fixed, it would be possible to add new accumulators such as rolling_mean_of_weights, rolling_mean_of_variates, analogous to mean_of_weights, mean_of_variates.
