Purpose: Encapsulates most of the features of a Gamry Instruments potentiostat/galvanostat .
It is used to provide control over a potentiostat and to keep two experiments from trying to share the same potentiostat.
Usage: The PSTAT class is not actually used in practice. Rather, it is a phantom class that is superseded by the actual class of potentiostat, e.g., PC5.
Each of the instance functions described in this help would actually pertain to a PC5 class, and not a phantom PSTAT class.
