CheckUserLog is a variable that "points to" a file which will be used as a log for queries launched under the extension. To set up a log:

 * 2) Create a .txt file in the folder where the CheckUser extension files are: for example, in /extensions/CheckUser, create /extensions/CheckUser/CheckUser-log.txt
