[Ifeffit] multiple k-weights refinments

I try multiple k-weights refinments with ARTEMIS of Al K EXAFS of ternary aluminium and titanium nitrides films. This system is rather disordered and textured with large grain boundaries that contribute to EXAFS. Consequently only few parameters can be varied simultaneously. I think that the k**3 weighting plays the major role in the multiple k-weights calculation. There is no great dfference between the results of k**3 weight and multiple k-weights fits.
