title: Laravel 4 - Migrations 'Blueprint' meaning?
body: <p>I need a bit of advice.</p>
  
  <p>I have a few migrations files in my setup.</p>
  
  <p>In some of them im seeing the following code which arent in the rest and im not sure what its for</p>
  
  <pre><code>use Illuminate\Database\Schema\Blueprint;
  Schema::create('brand', function(Blueprint $table)
  </code></pre>
  
  <p>Could anyone tell me what the blueprint lines are for? as they arent in the other create table migrations.</p>
  
  <p>Thanks</p>
