Fixes for the N_state_model.test_stereochem_analysis system test for the new normalised NOE plots.

Removed 'subdivide_grid' from the __all__ list.

Deleted the generic_fns.subdivide_grid module.

The multi-processing code is fully functional without it as the functionality has been shifted to
minfx.

PrependOut.write() now flushes both STDOUT and STDERR giving perfect interleaving of the 2 streams.

Fixes and simplification of the PrependOut class.

Much code and comments have been deleted to significantly simplify this class. The stream is now
flushed with a flush() call. This fixes the problem of STDERR and STDOUT interleaving!

Fix for the _disassemble_result() method for when there is no chi2 variable present.

Modified _disassemble_result() to be parallelisation friendly.

Optimisation results are only stored if the chi2 value is lower!

The subdivided grid search is now activated in the MF_grid_command class.

Switched from using Grid_info to minfx.grid.grid_split().

The model-free grid search 'command' will need to be modified to utilise this.

The Info_box.package_info() has been added to provide package information.

This is show with the -i cmdline option. The following packages are currently reported:
