renames loop_db to hopefully more descriptive testset_mll, adds a todo in get_pred for when I write that test, and fixes a coding hole inside testset_mll that resulted in the deletion of the training db when train==test (since removing a single test case from the train db means it needs to be present in the following loop when a different case is chosen)
