body: <p>Is there a way to have Singularity automatically generate a set of available classes based on the number of grid columns?</p>
  
  <pre><code>$grids: 12;
  
  .span1-1 { @include grid-span(1,1);}
  .span1-2 { @include grid-span(1,2);}
  .span1-3 { @include grid-span(1,3);}
  ...
  .span11-1 { @include grid-span(11,1);}
  .span12 { @include grid-span(12);}
  </code></pre>
