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().

Merged the Base_value, Float, Integer, and String wizard elements together into the single Value class.

This simplifies the code, as the differences between them was very minor.

Floats and tuples of numbers are now supported by the user function GUI argument elements.

General clean up.

Whitespace clean up.

The align_tensor.display user function backend arg is now a keyword arg.

This is for supporting the auto-generated user functions.

Fix for the auto-generated user functions - the argument defaults are now properly set.
