+    eeprom_get example.
+ 
+    This shows how to use the EEPROM.get() method.
+    
+    To pre-set the EEPROM data, run the example sketch eeprom_put.
+    This sketch will run without it, however, the values shown 
+    will be shown from what ever is already on the EEPROM.
+    
+    This may cause the serial object to print out a large string
+    of garbage if there is no null character inside one of the strings
+    loaded.
