/**
 * Simple MultiLogChannel that takes the logdata, formats it textually, and
 * writes it to a text device, either a file or the screen, yay!  This takes
 * the place of the old standard logging facility.
 * The entries in the format follow the standard printf % style, and are as
 * follows:
 * <ul>
 *  <li>%y - current year</li>
 *  <li>%m - current month</li>
 *  <li>%d - current day</li>
 *  <li>%h - current hour (24-hour format)</li>
 *  <li>%M - current minute</li>
 *  <li>%s - current seccond</li>
 *  <li>%l - Loglevel (numerical)</li>
 *  <li>%f - Filename</li>
 *  <li>%L - Line number</li>
 *  <li>%t - Full text of the log entry</li>
 * </ul>
