* 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
