Anonymous Associations

Since Associations are Items and the Name field is optional for Items, it is possible to have Anonymous Associations. Such a creature is useful if, for example, you just want to say that a group of things are related. E.g., I just select a bunch of photos from my bike tour and say that they are related. Sure, I *could* say that they have the name "bike tour", but why? I should just be able to associate them and not have to worry about naming immediately, especially since I can get an Item's Associations from the Item itself.
