title: Django-import-export - export from model's functions?
body: <p>For a Django model I'm using django-import-export package.</p>
  
  <p>The manual says I can export fields that are not existing in the target model like so:</p>
  
  <pre><code>from import_export import fields
  
  class BookResource(resources.ModelResource):
      myfield = fields.Field(column_name='myfield')
  
      class Meta:
          model = Book
  </code></pre>

  <p>How do I export the output of functions from the model?  e.g. Book.firstword()</p>
