+  Reading and writing to flash using the EEPROM library

+
+  SparkFun labored with love to create this code. Feel like supporting open source hardware?
+  Buy a board from SparkFun! https://www.sparkfun.com/products/15376
+
+  This example shows how to use the EEPROM get and put functions
+  to read and write to EEPROM inside Artemis.
+
+  Artemis doesn't actually have EEPROM. Instead we are writing to a protected
+  section of flash. 1028 bytes of flash are updated each time a variable is written. 
+  This can take up to 30ms.
+  
+  Page erase takes 15ms
+  Write byte takes 30ms - This is much longer than Arduino that takes 3.3ms
+  Float write across two words takes 30ms
+  Update (no write) takes 1ms
