Increment PtByPt (Not in Base Package)

Increments counter by one each time the VI is called when activate is set to TRUE.

activate, when TRUE, initiates an incremental count. When FALSE, the VI does not count.
initialize, when TRUE, initializes the internal state of the VI.
counter is the incremental value where counter = previous counter + 1. The default is 1. The value of counter changes only after you set activate to TRUE.
overflow is FALSE by default. If counter reaches overflow, overflow becomes TRUE and causes the value of counter to become 1 again.
