relax SVN archive

Deleted the now unused __do_layout() method.

A few unused sizers were inside this method.

Shifted a property into add_relax_data_input() that had not been already moved.

Spun out the rest of the automatic model-free analysis code out into methods.

The new methods include:
add_execute_relax()
add_mf_models()
add_modsel_method()
add_pdb_selection()
add_results_dir()
add_unresolved_spins()

Shifted a few variable of add_relax_data_input() back into the class namespace.

This allows the methods bound to the buttons to function.

Shifted all the button action bindings into the add_relax_data_input() method.

Removed almost all of the variables in add_relax_data_input() out of the class namespace.

These now only exist temporarily in the method namespace, cleaning up the class namespace.

Transferred all the relaxation data input GUI elements into add_relax_data_input().

This method will later be broken up into other methods.

Created the add_frame_title() method.

The frame title is now created in this method and packed into which ever box is sent into the
method. The rest of the model-free GUI code has been commented out temporarily.

Wrote the build_right_box() method by collecting together all the sizer_15 lines.

Added epydoc documentation to the build_main_box() docstring.
