Same name and namespace in other branches

1. 7 performance.module \performance_average()

Calculate average. Note that this will always lose accuracy. In the 2.0 version we will NOT store the average anymore, but we will store the sum of all values and the number of accesses. That way we calculate the average when displaying without losing accuracy.
