* The class represents a Contiki filesystem, for example an EEPROM or external
* flash memory.
*
* It needs read/write access to the following core variables:
* <ul>
* <li>char[] simCFSData
* <li>char simCFSChanged (1=filesystem has been altered)
* <li>int simCFSRead (bytes read from filesystem)
* <li>int simCFSWritten (bytes written to filesystem)
* </ul>
* <p>
* Dependency core interfaces are:
* <ul>
* <li>cfs_interface
* </ul>
* <p>
* This observable is changed and notifies observers whenever the filesystem has
* been read from or written to.
