ks_rowscore return value

[tetomonti]

It appears that ks_rowscore returns a vector whose length and order do not (necessarily) match the input order (i.e., the order of FS_mat). This because it sorts the values (from largest to smallest) and removes the '0' p-values. This is not good practice: the function should return the vector with the same length and order as the input. The calling function will take care of sorting and filtering, if necessary.
