selection is slow, is there a way to improve it?

Using selection slow down the computation of a statistics. Using clever binning is much more efficient. Isn't it a way to improve how the selection is implemented?

Ok, I thought a bit about this, and it should improve soon since in the plotting, multiple selections are done in parallel. That means that it scales linearly in time with the number of selections, while actually it can be done in one go, so if I fix this it will go faster.

Apart from evaluating the selection, when a selection is used, the data is copied, instead, we could pass the mask array to the statisticNd algo (which does the binning), so that no copy of the data is made, this could speed up using selections alot I think.

Cleaning up issues, this is changed in master, performance is much better, feel free to reopen if still an issue.
