/*
strobePin has one of two formats:
1. if strobe pin is on uC (Scanner_uC or Scanner_ShiftRegsRead),
    then strobePin is an Arduino pin number connected to this row.
2. if strobe pin is on I/O expander (Scanner_IOE), then strobePin is bit pattern,
    1 indicating the I/O expander pin connected to this row

todo instantiation examples - here or in Scanner?
