+  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:
+ ** UNO:  MOSI - pin 11, MISO - pin 12, CLK - pin 13, CS - pin 4 (CS pin can be changed)
+  and pin #10 (SS) must be an output
+ ** Mega:  MOSI - pin 51, MISO - pin 50, CLK - pin 52, CS - pin 4 (CS pin can be changed)
+  and pin #52 (SS) must be an output
+ ** Leonardo: Connect to hardware SPI via the ICSP header
