/**
 * Logger - a very simple logger, mainly used during development.
 * Is not based on log4j (to reduce external dependencies).
 * However, if needed, something like log4j could easily be
 * hooked in.
 * <p>
 * For speed reasons, the static variables are not protected
 * with semaphores. In other words, if you dynamicaly change the
 * logging settings, then some threads may still use the old setting.
