Some code I want to put back later.

mc_work/unwanted.goat

+// altnewx is not used at the moment, but I will build a switch for it.
+// It is like newx, but moves all n dimensions a bit.
+func alt_newx(xold []float32, xT []float32, rand *rand.Rand, xDlta float32) {
+	for i, x := range xold {
+		t := 2.*rand.Float32() - 1
+		t *= xDlta
+		xT[i] = x + t
+	}
+}
