  Various types of elements can be present on a pipeline. 
    
  Blocks can have different states: idle, ready, or executed. These are color coded as
  <table cellspacing="3" class="body" cellpadding="2" border="1">
      <colgroup>
        <col width="10%"/>
        <col width="10%"/>

      </td>
      <td bgcolor="#35A400">
        <p>ready</p>
      </td>
      <td bgcolor="#CFBFFF">
        <p>executed</p>
      </td>
    </tr>
  </table>
  
  The following table describes these elements:
