e0a6e30581 Refactored the image pyramid code. Now there is just one templated object,
pyramid_down and you give it the downsampling amount as a template argument.

3e559e4292 Made find_min_box_constrained() and find_max_box_constrained() a little smarter
about how they schedule their initial step sizes.  In particular, they will try
to take step sizes that are similar to previously used sizes via a trust region
style scheduling.

8199ae1a48 Added another overload of poly_min_extrap() and also improved the speed of
backtracking_line_search() by making it use 3rd degree polynomial interpolation
after the first step.  Also made it more robust to alpha inputs with improper
signs.
