Class SetAccumulator

A SetAccumulator accumulates a bunch of objects and then makes an ImmuSet containing all the accumulated objects. Several people have observed that a SetAccumulator doesn't buy you much because instead you could just store into a MuSet. While this is true (and is in fact how SetAccumulator is trivially implemented), my feeling is that if what a loop is doing is enumerating a bunch of elements from which a Set is to be formed, using a SetAccumulator in the loops says this more clearly to readers of the code.
