title: How are codons read in Grammatical Evolution: are they a sliding window or are they done in chunks?
body: <p>I'm reading the paper by O'Neill and Ryan and they say this:</p>
  
  <blockquote>
    <p>each codon represents an integer value where codons are consecutive
    groups of 8 bits</p>
  </blockquote>
  
  <p>So I just want to make sure, two successive codons would be bits <code>1-8</code>, then <code>9-16</code> right? Or would they be bits <code>1-8</code>, <code>2-9</code>, <code>3-10</code> etc?</p>
