Reverted r10346 as the Bind() call should be to the main GUI class.

The command used was:
svn merge -r10346:10345 .

Turned the Auto_model_free class into a wx.Frame.

This is so that self.Bind() is functional.

Deleted all the non-model-free code from __do_layout().

Deleted all the non-model-free code from __set_properties().

Changed the scope of the model-free variables.

These were shifted from the relax_gui module namespace into the model-free class namespace. These
will eventually be shifted into the relax data store if any of these are not hardcoded.

Shifted panel_4 into the model-free class.

This seems to be the model-free panel!

Re-added the import of gui_bieri.paths.IMAGE_PATH.

Fixed the gui_bieri module imports.

Removed all the unused imports.

The main GUI class instance is now passed into the Auto_model_free class.

This will create a nested object tree structure so that all parts of the GUI can access all other
parts.
