title: django-import-export adding widgets to the model resource
body: <pre><code>class AccountResource(resources.ModelResource):
  
  class Meta:
      model = Account
      skip_unchanged = True
      report_skipped = False
      import_id_fields = ('ID',)
      fields = ('ID', 'Rank_Test', 'UName', 'DecimalTest')
  </code></pre>
  
  <p>Hello folks the above code is what I am using as my model resource for django-import-export. What I am trying to accomplish is that on import the 'DecimalTest' field uses the django-import-export decimal widget; this is because excel spits out all ints as a float. I am just unsure of how to apply the widget to the DecimalTest field in this context. Any help would be greatly appreciated.</p>
