title: Finding all instances of a string within a string
body: <p>What is a way that I can find (and loop through) all instances of a string within another string in lua? For example, if I have the string</p>
  
  <pre><code>"honewaidoneaeifjoneaowieone"
  </code></pre>
  
  <p>And I want to loop through all instances (and by this, I mean indexes) of "one" within that string, well, I can see that it appears four times, but I have no clue how to actually find them. I know that string.find() can find the first instance, but that doesn't help me very much.</p>
