This is discussed in the post https://mail.gna.org/public/relax-devel/2010-01/msg00075.html.
The aim is to have a single code base for the automatic protocols for all UI designs (prompt,
script, GUI, web interface, etc.). The API interface will be via class initialisations. The
automatic model-free protocol has been placed into the dAuvergne_protocol class.
Future aims of this code is to have the UI fill a single data pipe with all the data required for
the analysis, and then to pass in this pipe into the protocol. Then the auto-analysis will copy
this info into any other data pipes it requires. This will allow for better GUI interaction, data
display, etc.
