gov.fnal.eag.healpix.PixTools.intrs_intrv()
computes the intersection di of 2 intervals d1 (= [a1,b1]) and d2 (= [a2,b2]) on the periodic domain (=[A,B] where A and B arbitrary) ni is the resulting number of intervals (0,1, or 2) if a1 b1 then d1 = {x | a1 <=x <= B U A <=x <=b1} @param d1 double[] first interval @param d2 double[] second interval @return double[] one or two intervals intersections
