Title: added suggestion for nested Venn diagram using squares

Hi Konstantin,

what do you think about adding this diagram? It's for consecutive sub-selection (subsets of subsets), and also area-proportional. I used rounded squares.

call like so:

venn_nested(sets, labels = [r'$\mathbf{%s}$ ($%d$)' % (string.ascii_uppercase[i], len(s)) for i, s in enumerate(sets)])

Cheers,
Johannes
