stupid first thoughts about some set ordering interface thing

orderme.cs

public interface IOrderMe
{
    Order PreferredOrder();

    // or somethign like "void OrderMe(OrderContext relativeToOtherItems);"
}

public abstract class Order
{

}

public class Ordinal : Order
{
    // something, int probably
}

public class Relative : Order
{
    // something, little DSL probably
}

public class Irrelevant : Order
{
        
}
