title: Relationship between LR(0), LL(0), LALR(1), etc?
body: <p>I'm really struggling to unterstand the relationship between:</p>
  
  <ul>
  <li>LR(0)</li>
  <li>LL(0) </li>
  <li>LALR(1)</li>
  <li>SLR(1)</li>
  <li>LR(1)</li>
  <li>LL(1)</li>
  </ul>
  
  <p>I'm pretty sure LALR(1) and SLR(1) are subsets of LR(1), but I'm lost about the others. Are they all exclusive? Is LL(0) a subset of LL(1)?</p>
  
  <p>Thanks</p>
