Updated the Palmer.test_palmer_omp system test for the 64-bit Linux Modelfree 4.20 GCC binary file.

This fixes the second part and last part of the bug #22772 (https://gna.org/bugs/?22772), the
modelfree4 binary issue and the User_functions GUI tests with wxPython 2.9 failures of the test
suite.

The problem is that the 64-bit GNU/Linux GCC compiled binary of Modelfree 4.20 produces different
results as previous versions. These are now caught by the system test and correctly checked.

Fix for the poorly written User_functions.test_structure_add_atom GUI test.

This fixes one part of 2 of the bug #22772 (https://gna.org/bugs/?22772), the modelfree4 binary
issue and the User_functions GUI tests with wxPython 2.9 failures of the test suite.

The problem was that a list element was being set in the GUI test, but that element did not exist
yet. Somehow this worked in wxPython 2.8. But the bad code failed on wxPython 2.9.

Improved the feedback in the User_functions.test_structure_add_atom system test.

It is now clearer what the input and output data is.

When issuing dx.map() function with points, implemented the writing out of parameter file, with associated calculated chi2 values.

Modified that structure of points in dx.map() is always a list of numpy arrays with 3 values.

Added boolean argument to dx.map() function, to specify the creation of a parameter and associated chi2 values file.

For very very special situtaions, the creation of this file is not desired.

Added example save state for more surface plotting.

Added example surface chi2 values for plots.

Task #7826 (https://gna.org/task/index.php?7826): Write an python class for the repeated analysis of dispersion data.

Added scripts to make surface plots of spin independents parameters dw and r2a.

Renamed sample scripts making surface maps.
