SD card storage for micro:bian

Abstract
The interface for SD cards is a variant of SPI, and they have a well-documented protocol. Implement a block storage service
that uses this interface, and on top of it a file system, choosing either the MS-DOS disk format or the one used by Minix,
either of which will allow the cards to be mounted on a Linux host. Open source implementations of the MS-DOS file system
exist in the Arduino world as a guide.
