Commented out some non-functional code.

Added a missing import from 'path'.

Fixed all the gui_bieri module imports.

Cleaned up and removed all unused imports.

Create the Auto_r1 class for building the automatic R1 analysis frame.

This inherits from Auto_rx, so needs to provide only a few hardcoded class variables.

Renamed the class from Rx to Auto_rx.

Deleted large amounts of old relax_gui code.

Fixed the auto_model_free module docstring, it was still that of relax_gui.

Copied gui_bieri.relax_gui to gui_bieri.analyses.auto_rx_base to prepare to spin out the R1 and R2.

The code has not changed yet. This will be a base class for all R1 and R2 analyses, as most of that
code is identical and can be shared.

Added the full resolution image of the Ulysses butterfly that is the relax logo.
