A CharacterController based controller for use in Unity's new Networking system.

End-of-life

Up to 1 millisecond on server every time a network update happens.
Up to 1 millisecond on client every time a network update happens. Sometimes it jumps a bit higher if there are a lot of inputs to replay during reconciliation. That is due to high latency.
Very small overhead on non local clients moving.
GC allocations 80 bytes per player. This is due to CharacterController.
Way higher GC allocations on the server side (and while recording gameplay for that matter), due to the need of storing history of the objects for lag compensation.

It moves character only when network update occurs and then interpolate until the next network update in LateUpdate.
Efficiend data reusing with as least locals as possible (as they cause GC allocations).

Update Once and Lerp mode does not work well with the update rates over 50hz. Use lower send rate or a higher one with Update Once mode.

Add jumping between updates so jumping would feel good even on small update periods.
Complete lag compensation.
Fix issues.
