Simplification of the GUI analysis post_reset() method.

This now uses the delete_all() and hence delete_analysis() methods to clean up the GUI. The reset
argument has been added to skip the manipulation of relax data store data, as the data store is
empty after a reset. However the calling of the delete_analysis() method now ensures that the
analysis specific delete() method is now called so that the GUI elements can be properly destroyed.

Shifted the printouts from the GUI tests suite clean_up_windows() method to the tearDown() method.

This change means that the printouts are not within a wx.CallAfter() call, but rather at the end of
the tearDown() method just prior to starting the next test.

Spacing printout for the list of still open GUI window elements.

This is for the GUI test tearDown() method.

More fixes for the user function GUI object Destroy() method.

This page GUI object is destroyed by the wizard window Destroy() method, so destroying again causes
wxPython runtime errors.

Fixes for the user function GUI object Destroy() method.

This matches the code just deleted in the GUI test suite tearDown() method for handing the user
function page object.

The GUI test suite tearDown() method now calls the user function GUI wizard Destroy() method.

This is for better handling of user function elimination.

Fixes for the custom Wiz_window.Destroy() method.

This will now first close the wizard window via the Close() method to make sure all of the wizard
pages are properly updated. In the end the wizard DestroyChildren() method is called to clean up
all child wx objects, and finally Destroy() is called to eliminate the wizard GUI object.

Import fix and copyright update.

Modified the GUI test suite tearDown() method.

The clean_up_windows() method called by tearDown() now prints out a lost of all of the living
windows instead of trying to destroy them (which causes the running of the GUI tests in the GUI to
cause the GUI to be destroyed). The printouts will be used for debugging purposes.

Modified the GUI test suite _execute_uf() method.

This user function execution method now calls the user function GUI object Destroy() method to clean
up all GUI objects. This should save memory for GUI objects in the GUI test suite.
