+  How similar are two texts?  The approach used here relies on co-occurrence
+  matrices and is very efficient.
+
+  Let's see with an example: how similar are "here" and "hither"?  The
+  co-occurrence matrix M for "here" is M[h,e] = 1, M[e,r] = 1, M[r,e] = 1, and 0
+  elsewhere; the matrix N for "hither" is N[h,i] = 1, N[i,t] = 1, ...,
+  N[h,e] = 1, N[e,r] = 1, and 0 elsewhere.  The union U of both matrices is the
+  matrix U[i,j] = max { M[i,j], N[i,j] }, and the intersection V is
+  V[i,j] = min { M[i,j], N[i,j] }.  The score for a pair of texts is
+
+      score = (sum of V[i,j] over all i, j) / (sum of U[i,j] over all i, j),
+
+  a formula suggested by Arnt Gulbrandsen.  Here we have
+
+      score = 2 / 6,
+
+  or one third.
+
+  The implementation differs from this in a few details.  Most importantly,
+  repetitions are ignored; for input "xxx", M[x,x] equals 1, not 2.
