Detailed Description

Replace elements with normalized rank.

Each element x is replaced by $ \frac{\sum I(x_i-x) w_i}{\sum w_i} $ where $ I(x) = 1 $ for $ x>0 $, $I(x) = 0.5 $ for $ x=0 $, and $ I(x) = 0 $ for $ x<0 $.

It is possible to centralize a range "in place"; it is permissible for the iterators first and result to be the same.
