* The functions txBegin and txEnd are used to transactionate the loggable.
* When a new transaction is created, they add a txLevel because in some cases
* the transactions are performed in a recursive way.
*
* The function grabUserLog check if the option grabUser is active in the Model and
* login or logout the user in the database depending on the action.
*
* Now they are commented out because the way to handle the errors
* that occur in the database that leave opened transactions has not been found.
