str should be Str. Variables start with a capital letter.<br>

Why do I get: 49> chunks:chunks("Able was I ere I saw Elba."). **<br>
exception error: no function clause matching chunks:chunks("Able<br>
was I ere I saw Elba.") (chunks.erl, line 15) (Well, forget the<br>
like 15. I took out a bunch of comments.)<br>
