Updated exchange point cross-matrix

I have updated my exchange point cross-matrix. I didn't bother to update the ASN/name index because I thought it would be faster just to let you send in corrections. I have no idea which ASN or name some people are going to use pre/post merger. http://dranet.dra.com/exchangematrix.html -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
