 Instantiation
 -------------
 Definition of DELAY_MICROSECONDS is explained in RowBase.cpp.
 todo Definition of activeHigh is explained in RowScanner_Interface.h
 Example instantiation of a row:
 const unsigned int RowBase::DELAY_MICROSECONDS = 1000;
 const bool RowScanner_PinsArray::activeHigh = 0;
 const bool RowScanner_PinsArray::STROBE_ON = LOW; //logic level of strobe on
 const bool RowScanner_PinsArray::STROBE_OFF = HIGH; //logic level of strobe off
 const uint8_t colPins[] = {0,1,2,3,7,8};
 const uint8_t COL_PIN_COUNT = sizeof(colPins)/sizeof(*colPins);

 Using smaller types on a 32-bit uC (Teensy LC) would accomplish nothing.
