Hi @Sebastien Gouezel. Sorry if I've already asked this before. Why did you chose to have docs#charted_space.atlas? Is it better than dealing with docs#charted_space.chart_at only?

I am thinking of situations where there is a natural atlas, but where the elements of this atlas are not naturally parameterized by points in the manifold. Then having only the chart_at as members of the atlas would be very artificial.
