HMF second draft

I got Tsalmantza and my HMF method paper up to the second-draft level. I was supposed to finish this back in October! It still needs a bit of work—Tsalmantza and I speak with very different voices—but it is extremely close. One thing the paper lacks is a clear demonstration that optimizing chi-squared is far preferable to optimizing an unscaled mean square error. I guess we always considered that obvious, but I now wonder if everyone else does.
