Using Functions

Introduction to Haskell, Part 2: Pure Functions, linked on the class site, 
shows how to program in a functional language by writing functions.  The 
example used is to list the top ten words in a text in order of frequency. 

Write an Erlang program to list the top ten words and their frequencies in 
a given text.  Use the novel Emma by Jane Austen which is linked on the 
class site. 

My program is 26 lines exclusive of comments.  I used recursion and list 
comprehensions. I wrote six functions and used file:read_file, file:close, 
binary_to_list, string:tokens, string:to_lower, lists:sort, lists:splitwith, 
lists:last, lists:reverse, and lists:sublist.
