title: What is the default padding for int field in BeanIO?
body: <p>What is the default padding for <em>int</em> field in BeanIO if nothing is specified? For example in the following case:</p>
  
  <p>Here I do not have padding mentioned for <strong>salary</strong> field, so what would be the value when marshalled to stream for <code>salary=8888</code>?
  Will it be <code>008888</code> or <code>8888</code> (2 spaces followed by 8888)?</p>
  
  <pre><code>  &lt;stream name="employeeFile"&gt;
      &lt;record name="employee" class="example.Employee"&gt;
        &lt;field name="firstName" length="10" /&gt;
        &lt;field name="salary" length="6" justify="right" /&gt;
      &lt;/record&gt; 
    &lt;/stream&gt;
  </code></pre>
