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:
minfx
bmrblib
numpy
Numeric
ScientificPython
wxPython
mpi4py
scons
epydoc

Replaced the relax version line with the full relax intro when using the -i cmdline flag.

Renamed Info_box.print_sys_info() to Info_box.sys_info().

The method now returns the info string, and this is printed later.

Shifted the relax intro string (written to STDOUT) from the interpreter module to the Info_box.

Added the -i or --info option to relax.

This causes all of the information about relax and Python to be printed by calling
Info_box.print_sys_info(). This option will be useful for determining issues with relax installs!

Changed the axis ranges for the RDC Q-factor vs. NOE Q-factor correlation plot.

Fixed the x-axis label for the scaled Q-factor vs. Q-factor correlation plot.

Completed the Stereochem_analysis.__init__() docstring, adding all the epydoc tags.
