STK_PARETOFIND finds non-dominated rows in an array
CALL: [NDPOS, DRANK] = stk_paretofind (X)
returns the indices NDPOS such that X(NDPOS, :) contains all non-
dominated rows of X, sorted in (ascending) lexical order. A row
X(i, :) is said to dominate another row X(j, :) if
X(i, k) <= X(j, k) for all k in {1, 2, ..., d}
and
X(i, k) < X(j, k) for at least one such k,
where d is the number of columns. In other words: smaller is better.
For each row X(i, :), DRANK(i) is equal to zero if the row is non-
dominated, and equal to the smallest j such that X(i, :) is dominated
by X(NDPOS(j), :) otherwise.
