body: <p>Does the OrmLite CreateIndex API support multicolumn index?</p>
  
  <p>It looks like it accepts just once column parameter:</p>
  
  <pre><code>db.CreateIndex&lt;Table&gt;(x =&gt; x.ColumnName);
  </code></pre>
  
  <p>Also is it possible to specifcy ascending/descending or nulls last?</p>
