Detailed Description

This control's microchip's AT25M02 EEPROM Device. This treats it as a circular queue, and will not overwrite existing data.

I (Sean) had to move initialization code out of the constructor because the compiler does not like initializing SPI in the constructor It seems like most of this is written for the old version of the Arduino SPI library - probably a good idea too go through and fix that at some point.
