This program when uploaded and run burns two classes of data into the mini-pro 2K byte EEPROM.
1. Constant strings to minimize memory use since this is severely compromised by the display buffer.
2. Preference values which may be changes during program execution. On a re-run these last 6 statements my be commented out to preserve existing values.
After executing this program the service program must be re-uploaded and run.
The structs must be replicated exactly in the service program or the EEPROM.get() will fail.
