 *  \section Sec_Description Project Description:
 *
 *  Firmware for a USB AVR powered USB TTL magnetic stripe reader (using a card
 *  reader such as the Omron V3B-4K) by Denver Gingerich. This project is designed
 *  to be used with the open source Stripe Snoop project at <a>http://stripesnoop.sourceforge.net/</a>.
 *
 *  See <a>http://ossguy.com/ss_usb/</a> for the USB reader hardware project website,
 *  including construction and support details.
 *
 *  To use, connect your magnetic card reader device to the USB AVR as follows (pin and port mapping may be adjusted
 *  from the project makefile):
 *
 *  <table>
 *   <tr>
 *    <th><b>Signal:</b></th>
 *    <th><b>AVR Port:</b></th>
 *   </tr>
 *   <tr>
 *    <td>Track 1 Data</td>
 *    <td>PORTC, Pin 1</td>
 *   </tr>
 *   <tr>
 *    <td>Track 1 Clock</td>
 *    <td>PORTC, Pin 2</td>
 *   </tr>
 *   <tr>
 *    <td>Track 2 Data</td>
 *    <td>PORTC, Pin 3</td>
 *   </tr>
 *   <tr>
 *    <td>Track 2 Clock</td>
 *    <td>PORTC, Pin 0</td>
 *   </tr>
 *   <tr>
 *    <td>Track 3 Data</td>
 *    <td>PORTC, Pin 5</td>
 *   </tr>
 *   <tr>
 *    <td>Track 3 Clock</td>
 *    <td>PORTC, Pin 6</td>
 *   </tr>
 *   <tr>
 *    <td>Card Detect</td>
 *    <td>PORTC, Pin 4</td>
 *   </tr>
 *  </table>
 *
 *  This project is based on the LUFA Keyboard project demonstration application, written by Denver Gingerich.
 *
 *  This application uses a keyboard HID driver to communicate the data collected a TTL magnetic stripe reader
 *  to the connected computer. The raw bitstream obtained from the magnetic stripe reader is "typed" through
 *  the keyboard driver as 0's and 1's. After every card swipe, the project will send a return key.
