This was proposed by Edward.

Added references and instructions in the sample script for consistency testing.

This is as proposed by Edward in a post at:

(Message-id: <7f080ed10911180653w6b59b40dn1e8f715d9b718fd5@...>)

Added references to the consistency tests code.

In particular, the reference for this newly published paper was added:
Morin & Gagne (2009) JBNMR, 45: 361-372.

Created a branch for Michael Bieri's (michael.bieri@...) GHI for relax
O

Implemented the get_peak_intensity_type() method for returning that data.

The relax_data.peak_intensity_type() user function is now fully operational.

The BMRB system test has been repaired for the user function argument name change.

Added the interface for the relax_data.peak_intensity_type() user function.

The peak intensity type is now being passed into the BMRB file.

This doesn't work yet as the user function doesn't exist!

Added the specification of the peak intensity type to the BMRB system test.

Solved an issue created during the merge process (r9863) concerning the 'return_data_name_doc' call.

The solution is based on the code in 'specific_fns/relax_fit.py'.
