Hello,

here is a new version of the patch.

I could have made abs_knowing_score safe against users specializing scalar_score_coeff_op as a derived class of a default scalar_score_coeff_op for a different type, but I don't think it is necessary. Also, I don't really know where to put abs_knowing_score, it is not a unary functor, but moving it far from scalar_score_coeff_op seems strange. And should it appear in the doc? For now I made it so it doesn't. I rely on the compiler eliminating dead code for abs_knowing_score, making the access to the coefficient lazy is more complicated and, I think, unnecessary.
