If all you have is a bunch of functions, just sticking them in a module 
is fine.  The reason you would want to package them up as a class would 
be if there's some state that needs to be saved.

Don't think of a class as a collection of methods, think of it as a hunk 
of data, and some methods which operate on that data.  Looking at it 
another way, if you write a class and discover that none of the methods 
ever make any use of self, then what you probably really wanted to do 
was create a module to hold all those methods as top-level functions.
