ability to delete image collection or a specific category for a given image collection

[joefutrelle]

This would be on an admin page where a user could select an image collection an optionally a label, and the result would be

• deleting all annotations for that image collection (optionally just the ones with the given label) from the db
• deleting all ROIs that are "orphaned" by this process (e.g., delete the ROI record from the db, but don't delete the image on disk)

The user req driving this is that a user may want to work temporarily and then clean up their work after they export what they need. Or for instance there's a huge category, the user sorts selected ROIs out of it, then they want to delete that category. Mostly to not clutter up the UI with work that's been completed, but also to keep the database smaller and thereby improve performance.

@joefutrelle What if they try to delete either a collection or a label that was done by someone else? E.g, I add the collection, and annotate a few things. Heidi goes in and does some as well. Can I still delete the collection or labels, even though some of them would be Heidi's?

This is intended to be a "big hammer" and so a user with privileges to do this (basically anyone who can annotate) will be able to perform these operations regardless of who had worked on that collection/label.

Got it. I think it requires a confirmation message (obviously), but with other project we included some of the details of what was being removed. E.g, something like:

Along with your XXX annotations, there are XXX annotations from other users that will also be deleted. Are you sure you want to delete this image collection?

Good idea.
