Michael Shimniok / Mbed 2 deprecated SDCardShell

Demonstration of a very simple unix-like shell. Based on integrating both Klaus Bu\'s SDHCFileSystem and the FATFileSystem library out of Thomas Hamilton\'s SDCard program. Result: you get high capacity + a plethora of filesystem functions.

Dependencies:   mbed
