Added extensive sectioning printouts to the dauvergne_protocol model-free auto-analysis.

The lib.text.section functions title() and subtitle() are now used to mark out all parts of the
auto-analysis. This will allow for a much better understanding of the log files produced by this
auto-analysis.

Changed the model-free single spin optimisation title printouts.

The specific_analyses.model_free.optimisation.spin_print() function has been deleted. It has
instead been replaced by a call to lib.text.sectioning.subtitle(). This is to match the grid search
setup title printouts and to differentiate these titles from those printed out by minfx being
underlined by '~' characters.

Alphabetical ordering of imports in the dauvergne_protocol model-free auto-analysis.

Added printouts to the determine_rnd() function of the dauvergne_protocol model-free auto-analysis.

This is for better user feedback in the log files as to what is happening. It may help in debugging
bug #22730 (https://gna.org/bugs/?22730): Model-free auto-analysis - relax stops and quits at the
polate step.

Added an additional check to determine_rnd() of the dauvergne_protocol model-free auto-analysis.

This is to try to catch bizarre situations such as bug #22730 (https://gna.org/bugs/?22730),
model-free auto-analysis - relax stops and quits at the polate step.

The additional check is that if the base model directory is not executable, a RelaxError is raised.

Added more checks to the determine_rnd() of the dauvergne_protocol model-free auto-analysis.

This is to try to catch bizarre situations such as bug #22730 (https://gna.org/bugs/?22730),
model-free auto-analysis - relax stops and quits at the polate step.

The following additional fatal conditions are now checked for: A file with the same name as the
base model directory already exists; The base model directory is not readable; The base model
directory is not writable. The last two could be caused by file system corruptions. In addition,
the presence of the base model directory is checked for using os.path.isdir() rather than catching
errors coming out of the os.listdir() function. These changes should make the analysis more robust
in the presence of 'strangeness'.

Renaming of the 'dx' user function class to 'mapping'.

In addition, the dx.map user function is now called mapping.setup and the dx.execute user function
is now mapping.dx_execute.

Initialized merge tracking via "svnmerge" with revisions "1-26279" from

Creating a quick branch for refactoring the space mapping code.

This follows from the discussion in the thread at
http://thread.gmane.org/gmane.science.nmr.relax.scm/24009/focus=7228.

The idea is to create a number of software independent and dependent user functions for setting up
the space mapping (the map.setup user function), creating the map, storing all data in the current
data pipe, and having user functions for outputting the data for OpenDX, matplotlib and plain text.

Narrowed in dx_map in systemtest Relax_disp.test_dx_map_clustered_create_par_file()

This is to illustrate the failure of relax finding the global minimum.

It seems there is a shallow barrier, which relax failed to climb over, in order to find the minimum value.

Added the verbosity argument to the pipe_control.minimise.reset_min_stats() function.

All of the minimisation code which calls this now send in their verbosity arguments. This allows
the text "Resetting the minimisation statistics." to be suppressed.

Added the verbosity argument to the pipe_control.value.set() function.

This is passed into the pipe_control.minimise.reset_min_stats() function so its printouts can be
silenced.

r26267 | bugman | 2014-10-13 22:59:51 +0200 (Mon, 13 Oct 2014) | 6 lines

The pipe_control.opendx space mapping code now calls the value.set() function with verbosity=0.

This is to silence the very repetitive statistics resetting messages when executing the dx.map user
function.
