charles young / Mbed 2 deprecated GEO_COUNTER_L432KC

Charles Young's development fork. Going forward I only want to push mature code to main repository.

Dependencies:   mbed

Fork of GEO_COUNTER_L432KC by Geo Electronics "Geo Counter"

Still developing mode selection.  LEDs turn off when not in mode selection.  Pressing once enters mode selection. Pressing again enters submode.  Temporarily the rotary switcha adjusts the display brightness.  This is just for testing.

Who changed what in which revision?
