the server side now returns the list of all items for the seller.
removing extraneous angular view.
A seller can now see a list of all of their listings.
Made a bit of progress on the UI for creating a listing.  Also, added a method to the brand to find by name which is case insensitive.  I'll be using that for the next step which is the controller to save the listing.
sellers can now create listings, and we do deduplication on teh brand names in a case insensitive manner.
