crossfilter.all() not working as per the docs + cf.size works
<p>as per the <a href="https://github.com/crossfilter/crossfilter/wiki/API-Reference#crossfilter_all" rel="nofollow">docs</a> I cannot get <code>cf.all()</code> to work</p>

<p>I am using this as an example <a href="http://animateddata.co.uk/articles/crossfilter/" rel="nofollow">here</a> in the console in the broswer.</p>

<p>This is what i see in the console. </p>

<pre><code>cf
Object {}
cf.all()
VM1818:1 Uncaught TypeError: cf.all is not a function(…)(anonymous function) @ VM1818:1
cf.size()
2692
</code></pre>

<p>I can get <code>cf.size()</code> to work but not <code>cf.all()</code></p>
