Removed the now useless 'functions' module.

The Bmrb.test_bmrb_rw GUI test is now complete and fully uses the new auto-generated user functions.

This test will only pass once all the relevant user functions are converted to the auto-generation
design!

The 2D sequence args of the auto-generated GUI user functions now matches the normal sequence elements.

The String_list_of_lists_window has been converted to Sequence_window_2D which inherits from
Sequence_window. All Python types and sequences supported by the Sequence GUI element are now
supported by the Sequence_2D element (which is the old String_list_of_lists).

Removal of a debugging print out.

Converted all of the align_tensor user functions to the auto-generation design.

Fix for the Combo_list GUI element - all of the combo boxes are now properly updated with values and data.

Fix for the Uf_page.on_display() method for choice iterators which return strings.

Strings are a sequence type, so len() is not a valid test!

Merged all of the sequence wizard page GUI elements into one.

This is to significantly simplify the code.

Added GUI conversion functions for tuples.

Better checking of the contents of the GUI element by Value.GetValue().
