How to implement a word counter - function ''compute_word_frequencies''

Imagine a text file ''example.txt'' that contains:
<code>
one
one two
one two three
one two three four
</code>


<code python>
>>> from texttools import compute_word_frequencies
>>> compute_word_frequencies('example.txt')
{'one': 4, 'two': 3, 'three': 2, 'four': 1}
</code>
