This Log object should help to detect the usage of deprecated code.
The main reason for this class is the lack of a "deprecated concept"
for tag libraries. Thought the designer of a Tobago page cannot see
in his IDE that a tag or attribute is deprecated.
The Tobago Java code will log into this Log object, with
error
- when the code is deprecated with a loss of function, or
warn
- when the code is deprecated, but still works.
This Log category can be switched off, in production environment without
affecting the normal logging category.
