Fixed bad code

Used synchronized() with iterator in Timer.Java
Did a similar synch in TimeMessagePairs
Cleaned up some of the code it Timer…. removed nested loop. The while()
should be more-or-less linear now on k where k = n + m | n = # of
elemens in TimeMessageVec and m = numerator value.

Also, removed a DUPLICATE LOOP!!!! Numerator calculations on beat was
done before and after vector iteration… there’s no need to.
