 *  <p>Ensures debug levels are set and defines debug functions.</p>
 *
 *  <p>General debug levels:</p>
 *
 *  <ul>
 *  <li>-1 - Run-time selected debug level.</li>
 *  <li>0 - No debug information.</li>
 *  <li>1 - Callbacks and timers.</li>
 *  <li>2 - Remote functions.</li>
 *  <li>3 - Stock functions.</li>
 *  <li>4 - Static functions.</li>
 *  <li>5 - Code.</li>
 *  <li>6 - Loops.</li>
 *  <li>7 - Extra loop code.</li>
 *  </ul>
 *
 *  <p>If you use <c>P:0</c> you get an optional debug print controlled by the
 *  global state <c>ysi_debug</c> - which is either on or off.</p>
