 *  \section Sec_Description Project Description:
 *
 *  Mass Storage device demonstration application. This gives a simple
 *  reference application for implementing a USB Mass Storage device using
 *  the basic USB UFI drivers in all modern OSes (i.e. no special drivers
 *  required).
 *
 *  On start-up the system will automatically enumerate and function as an
 *  external mass storage device which may be formatted and used in the same
 *  manner as commercial USB Mass Storage devices.
 *
 *  You will need to format the mass storage drive upon first run of this
 *  demonstration - as the device acts only as a data block transport between
 *  the host and the storage media, it does not matter what file system is used,
 *  as the data interpretation is performed by the host and not the USB device.
 *
 *  This demo is not restricted to only a single LUN (logical disk); by changing
 *  the TOTAL_LUNS value in DataflashManager.h, any number of LUNs can be used
 *  (from 1 to 255), with each LUN being allocated an equal portion of the available
 *  Dataflash memory.
 *
 *  The USB control endpoint is managed entirely by the library using endpoint
 *  interrupts, as the INTERRUPT_CONTROL_ENDPOINT option is enabled. This allows for
 *  the host to reset the Mass Storage device state during long transfers without
 *  the need for complicated polling logic.
 *
 *  \section Sec_Options Project Options
 *
 *  The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value.
 *
 *  <table>
 *   <tr>
 *    <th><b>Define Name:</b></th>
 *    <th><b>Location:</b></th>
 *    <th><b>Description:</b></th>
 *   </tr>
 *   <tr>
 *    <td>TOTAL_LUNS</td>
 *    <td>AppConfig.h</td>
 *    <td>Total number of Logical Units (drives) in the device. The total device capacity is shared equally between each drive -
 *        this can be set to any positive non-zero amount.</td>
 *   </tr>
 *   <tr>
 *    <td>DISK_READ_ONLY</td>
 *    <td>AppConfig.h</td>
 *    <td>Configuration define, indicating if the disk should be write protected or not.</td>
 *   </tr>
