Inform user and seller of bids that end
As a Buyer/Seller
I want to know when an item I am bidding or on I am selling runs out of bidding time and the result
So that I stay up to date on the items I am bidding and selling
I know I'm done when the system succesfully informs the Seller and Buyer of an ending listing and informs them of how it ended (Who bought, for how much, etc)
