  This library is based on several projects:
 
  The Arduino EEPROM library found here:  
  http://arduino.cc/en/Reference/EEPROM

  The 24C256 library found here:
  http://www.arduino.cc/playground/Code/I2CEEPROM

  The 24C512 library found here:
  http://www.arduino.cc/playground/Code/I2CEEPROM24LC512

  Our project page is here:

  From the datasheet:

  The AT24C1024B provides 1,048,576 bits of serial electrically 
  erasable and programmable read only memory (EEPROM) organized 
  as 131,072 words of 8 bits each. The device’s cascadable 
  feature allows up to four devices to share a common two-wire 
  bus.
