Improving interpolation

Here's how our new interpolation will work, inspired by the methods employed in the Source game engine:

• As we receive network states, we buffer them up
• Each network state is timestamped with network time
• We subtract a value from time to find a time in the past (in source, this value is 0.1 by default—so entities are always shown one tenth of a second in the past)
• We find the two states on either side of this time value, and interpolate between them
• Let's get started

First, we need some kind of struct to store a snapshot of the network state:

// a snapshot of values received over the network private struct networkState { public Vector3 Position; public double Timestamp; public networkState( Vector3 pos, double time ) { this.Position ...
