OSID - osid.room.construction.ProjectCampusAssignmentSession Service Interface Definition

Interface	osid.room.construction.ProjectCampusAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Projects` to `Campuses.` A `Project` may map to multiple `Campuses` and removing the last reference to a `Project` is the equivalent of deleting it. Each `Campus` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `Project` to another `Campus` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignProjects
Description	Tests if this user can alter project/campus mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping 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
Compliance	`mandatory`		This method must be implemented.
Method	canAssignProjectsToCampus
