Ideally I'd like to start with a scalar version using normal C arrays,
similar to the gsl_sum functions, for implementation simplicity.
Also, are the "exact/normtable" arguments essential or just for
convenience? If they can be computed easily by the user it would be
good to have only a minimal number of arguments in the base function.
