/**
 * This app shows the possibilities of the Simple|Silly File System.
 * The filesystem uses the external flash memory of the Spark-core to store files. it can store 16 files of max 64kB each.
 * I use it in a small webserver app I made; it works stable and is pretty fast.
 * This is the beta version, please informa me about hints and bugs: @marcus
 * enjoy!
