    /// Provides projection mapping from an IQueryable sourceto a target type.
    /// 
    /// This allows from strongly-typed mapping and querying only necessary fields from the database.
    /// It takes the place of Domain -> ViewModel mapping as it allows the ViewModel to stay as
    /// IQueryable.  AutoMapper works on in-memory objects and will pull all full records to perform
    /// a collection mapping.  Use AutoMapper for Input -> Domain scenarios, but not DAL.
