title: "For each" loop in a lua table with key value pairs
body: <p>Say I have a table defined like this:</p>
  
  <p><code>myTable = { myValue = nil, myOtherValue = nil}</code></p>
  
  <p>How would I iterate through it in a for each fashion loop like this?</p>
  
  <pre><code>  for key,value in myTable do --pseudocode
          value = "foobar"
    end
  </code></pre>
  
  <p>Also, if it helps, I don't really care about the key, just the value.</p>
