// - Adding a member to the well for this flag, and setting it in Schedule::handleWEFAC().
// - Making the wells' maximum flows (i.e. not time-averaged by using a efficiency factor)
// available and using those (for wells with WEFAC(3) true only) when accumulating group
// rates, but ONLY for network calculations.
