Curation Roles

Dryad curators need different roles to manage their work.

Senior Curator Role

 * moving items backward through the workflow
 * shopping cart actions (e.g. making vouchers)
 * Subset of communications (nuanced rejections)
 * withdrawing from repository
 * changing people’s contact information
 * edit all details of the transaction in the shopping cart

Junior curator role

 * typical forward progression approving items from blackout
 * subset of communications (obvious rejections: copyright notice, human subject data)
 * and anything not explicitly senior
 * view shopping cart

Other

 * Is there a need for the control panel to be visible to any curator? Should that only be for the (separate) admin?
