Created the RelaxListType class.

This generic list type with XML support will be used for storing the GUI info.

Shifted the rest of the menu related code into build_menu_bar().

This is just the bind actions. The menu bar can now easily be spun out into its own module.

Fixed the wx.Frame base class initialisation.

The previous code didn't do anything.

Shifted the creation of the menu bar from __init__() into build_menu_bar().

Added a docstring and comments to the Main.__init__() method.

The global LOCAL_TM variable has been shifted into a class level variable.

This variable is not too well used in the code base - presumably this code is incomplete.

Import fixes.

A few more variables from add_relax_data_input() were shifted back into the class namespace.

Access to the GUI elements storing data is required throughout. Eventually this data will be
temporary and only reflect the contents of the relax data store.

self is no longer passed into check_entries() as this is no longer a pseudo-method.

Shifted check_entries() and whichmodel() from select_model_calc to auto_model_free.

These are specific to the automatic model-free protocol, so do not need to be in a separate module.
They were also converted from functions to methods.
