G.9.3) GPS & Fishfinder v2

Following the intial version I decided to lose the LCD display and make the GPS / FF logging part of the box smaller.

For this I used the M44D40+ module  and PowerTwig from WBA Consulting. This allowed the functionality to be squeezed into a small project box, powered by a 9V battery. I should have included an on/off switch.

Changes to the code were minimal: re-assignment of the pin numbers in the 'constants' section and replacing the references to the LCD with an serial object so that data can be shown on a serial terminal for debugging.

A 'plug in' box with an LCD module wouldn't be beyond the realms of possibility.
