fminunc.m: Change algorithm defaults to match Matlab. * NEWS: Announce changes. * fminunc.m: Rewrite documentation. Change default options to match Matlab (TolX -> 1e-6 from 1e-7, TolFun -> 1e-6 from 1e-7, FinDiffType -> "forward" from "central", "MaxFunEVals" -> 100*number of variables from Inf. Adjust BIST tests to pass with new tolerances.
