Purpose: The CHRONOA class manages data-acquisition for a chronoamperometry curve.

There may be more than one data-acquisition object in a script, but only one may be running (i.e., acquiring values) at any time. The typical life-cycle of a ChronoA object is:

ChronoA = CHRONOA.New(Tag, Pstat) ; Create the ChronoA
ChronoA.SetPlot(Plottype)  ; Determine the plot type
ChronoA.Run()   ; Run the curve
ChronoA.Printl()   ; Print the curve out to Output

When a ChronoA object is run, the potentiostat must be in a Potentiostatic mode.
