[net.math] Algorithm for scheduling tennis matches

One solution to the problem that I get by fooling around with
matrices for a few minutes is this:

assume we have n players, with n even.
let d(i,j) be the day that the ith and jth players play.

then   d(i,j) = (i + j - 1) mod n-1  for i < j < n

and    d(i,n) = (2i - 1) mod n-1  for i < n
