Transaction Log Levels
----------------------

For users that have access to the ``data/Settings`` model,
the levels of logging can be managed. 

This level will affect the Log block of messages at the
bottom of a selected transaction on the Transaction interface and
does not for example affect the transaction or sub transaction Action and 
Detail information.

The levels includes messages as follows:

* Info - includes all messages
* Warning - includes Error and Warning messages
* Error - shows only error messages
* Disabled - disables all transaction log messages
