Added some clarifying comments.

Bug fix for the get_intro_string() method, intro_string is no longer a class variable.

Big clean up of the relax module.

This was quite messy, and should be good enough for merging once all the FIXMEs are eliminated.

Spelling fix for a function name.

Sorted all class methods alphabetically.

This will really help with code navigation and debugging.

Shifted the class Null_result_command to after Result_command due to it being a subclass.

Massive set of white space fixes!!!

This was a huge clean up!

Ordered all the classes alphabetically.

Shifted all functions to the top of the module and ordered them alphabetically.

Big reformatting of all the docstrings.

This includes much tidying up and making the formatting of the text consistent, many spelling fixes,
epydoc fixes, etc.
