+    eeprom_put example.
+    
+    This shows how to use the EEPROM.put() method.
+    Also, this sketch will pre-set the EEPROM data for the 
+    example sketch eeprom_get.
+    
+    Note, unlike the single byte version EEPROM.write(),
+    the put method will use update semantics. As in a byte
+    will only be written to the EEPROM if the data is actually
+    different.
