increase() function

increase() returns the cumulative sum of non-negative differences between subsequent values.

The primary use case for increase() is tracking changes in counter values which may wrap overtime when they hit a threshold or are reset. In the case of a wrap/reset, increase() assumes that the absolute delta between two points is at least their non-negative difference.
