"CD now prints the actual measured spawnrate after each wave.

It also prints how many zeds spawned, and how many cohorts or squads those zeds comprised.

Finally, it also prints how much time passed between the start of the wave and the first spawn, how much time passed between the first spawn and the last (this is the denominator in the spawnrate calculation), and how much time passed between the last zed spawn and the end of the wave."
