+ SD card basic file example
+
+ This example shows how to create and destroy an SD card file
+ The circuit:
+ * SD card attached to SPI bus as follows:
+ ** MOSI - pin 11
+ ** MISO - pin 12
+ ** CLK - pin 13
+ ** CS - pin 4
+
+ created Nov 2010
+ by David A. Mellis
+ updated 2 Dec 2010
+ by Tom Igoe
+
+ This example code is in the public domain.
