*
* PROTOLIB DEBUG LEVELS:
 *
 * @li PL_FATAL=0   // The FATAL level designates very severe error events that will presumably lead the application to abort.
 * @li PL_ERROR=1;  // The ERROR level designates error events that might still allow the application to continue running.
 * @li PL_WARN=2;   // The WARN level designates potentially harmful situations.
 * @li PL_INFO=3;   // The INFO level designates informational messages that highlight the progress of the application at coarse-grained level.
 * @li PL_DEBUG=4;  // The DEBUG level designates fine-grained informational events that are most useful to debug an application.
 * @li PL_TRACE=5;  // The TRACE level designates finer-grained informational events than the PL_DEBUG
 * @li PL_DETAIL=6; // The TRACE level designates even finer-grained informational events than the PL_TRACE
 * @li PL_MAX=7;    // Turn all comments on
 * @li PL_ALWAYS    // Messages at this level are always printed regardless of debug level
