New Revision: 27553
URL: http://svn.gna.org/viewcvs/relax?rev=27553&view=rev
Log:
Implemented the backend of the statistics.model user function.
The implementation heavily uses the specific analysis API, calling the
calculate(), model_loop(),
print_model_title(), model_statistics() and get_model_container() methods to do
all of the work.
The last of these API methods is yet to be implemented.
