I just realized there might have been an existing branch called "ta-seed", but looks like nothing has been changed on it. |

I believe you can just do [&]
to capture all the variables in the initializeRandomly
scope.

Actually, I think it should be std::mt19937 *rng
: use a pointer for i/o, not a reference. This should also be fixed in all other cases, but let's not add another case.
Updated translation averaging to use a random number generator (RNG) just like Shonan averaging.
