The GUI tests tearDown() method now prints out the Wizard windows title instead of name.

The GUI tests tearDown() method now prints out the Wizard windows names, if not destroyed.

Wizard window objects in the GUI can now be named.

This will help with debugging the GUI memory usage.

Improved memory management in the spin viewer window.

The spin loading wizard is now destroyed in the Destroy() method as well as before reinitialising
the wizard in the load_spins_wizard() method.

Changes for how the main GUI windows are destroyed by the GUI test tearDown() method.

These changes revert some of the code of previous commits. The recently introduced pipe editor and
results viewer windows Delete() methods have been deleted. Instead the Close() methods are called
in the tearDown() method to unregister the windows from the observer objects, followed by a
wx.Yield() call to flush the wx events, and then the clean_up_windows() GUI test base method is
called within a wx.CallAfter() call. This avoids the racing induced segfaults in the GUI tests.

Temporary disablement of the results viewer window destruction in the GUI tests.

This currently, for some unknown reason, causes segfault crashes of the GUI tests on Linux systems.

Fixes for the custom Destroy() methods for the pipe editor and results viewer GUI windows.

The event argument is now a keyword argument which defaults to None. This allows the Destroy()
methods to be called without arguments.

Improved memory management in the relaxation dispersion GUI analysis.

The dispersion model list window is now destroyed in the GUI analysis delete() method.

Created custom Destroy() methods for the pipe editor and results viewer GUI windows.

Improved memory management in the relaxation dispersion GUI analysis.

The peak intensity loading wizard is now properly destroyed. This is both via the delete() function
for terminating the analysis calling the wizard Delete() method, and in the peak_wizard_launch()
method calling the wizard Delete() method prior to overwriting the self.peak_wizard object with a
new GUI wizard.
