Book size penalty and book distance penalty configuration
Right now the penalty polynomials for distance and book set size are hard-coded in creativity/Reader.hpp, but they really should be configuration options.
Perhaps:
--utility-distance-penalty 1,2,3
(for 1+2d+3d^2 )
--utility-size-penalty 4,5,6,7
(for 4 + 5s + 6s^2 + 7s^3 )
