Not yet implemented in create and edit harvest source as they use the DGU forms API.
Also TODO, think of what report info is needed in the listing and details page.
This extension will hold all the harvesting code that is now located in
different parts of the ckan core and ckanext.dgu. This revision still
uses the ckanext-dgu forms API.
Controllers and templates have been defined for listing, creating and
showing the details of harvesting sources.
