Pinging mostly implemented.
Changed dbl quotes to single quotes.
Changes turn length after each ping on all peers.
Reset change in gruntfile.
Merge conflict.
Removed duplicate comm turn bug'
Fixed typo that prevented comm turns from running.
Sending and measuring acks.
Greatly reduced latency problems.  Reporting on 'inflated' turn time and peers that might be falling behind is reported but not used in Close Contact.  Users of CrunchJS can decide to act on that information without much trouble.
