+ * Logging class:
+ * - contains lfile, lwrite and lclose public methods
+ * - lfile sets path and name of log file
+ * - lwrite writes message to the log file (and implicitly opens log file)
+ * - lclose closes log file
+ * - first call of lwrite method will open log file implicitly
+ * - message is written with the following format: [d/M/Y:H:i:s] (script name) message
