Added screenshots of the spin viewer spin loading wizard sequence.read page.

Redesign of the data model chapter of the user manual.

This includes the moving of all of the spin viewer window text and screenshots from the NOE chapter.

Shifted the spin viewer screenshots into their own directory.

Changed the "View->Spin view" menu item to "View->Spin viewer".

Created a directory for screenshots of the spin viewer window operation.

Fix for the spin.create user function documentation - the prompt examples were wrong.

The NOE auto-analysis GUI test now checks the support for Trp indole N data as well.

The spectrum.read_intensities user function now prints out a list of the intensities read in.

This is for better user feedback as to what the user function has actually done.

Created the GUI wizard _apply() method for executing the current page's _apply() method.

This is for the GUI tests to simulate a click on the 'Apply' button.

Bug fix for the generic_fns.grace.get_data() function.
