Kernel::GenericInterface::Debugger
=head1 DESCRIPTION
GenericInterface data debugger interface.
For every communication process, one Kernel::GenericInterface::Debugger object
should be constructed and fed with data at the various stages
of the process. It will collect the data and write it into the database,
based on the configured debug level.
