Title: New tools

Hi Ted,Davide,Yossof,

Here are a couple cool new tools.

reweights is a class taking a step and a calculable (pointing to a list of weights) as a function. It does the step for each weight in the list.

There are also new functions in utils to divide or subtract a 2D histogram slice by slice.
