OSID - osid.bidding.BidAuctionHouseAssignmentSession Service Interface Definition

Interface	osid.bidding.BidAuctionHouseAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.bidding.BiddingManager`
Used By	`osid.bidding.BiddingProxyManager`
Description	This session provides methods to re-assign `Bids` to `AuctionHouse` mappings. A `Bid` may appear in multiple `AuctionHouse` objects and removing the last reference to a `Bid` is the equivalent of deleting it. Each `AuctionHouse` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `Bid` to another `AuctionHouse` is not a copy operation (eg: does not change its `Id`).
Method	canAssignBids

A return of false indicates that it is known item methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
