results, K parameters

[vitzwitz]

                           1. Am I remembering its purpose correctly?
                               - Once a pair is found (atom 1 near the Kth atom 2), KNN finds the other atoms
                                 in atom 2.
                               - If KNN fails to find the others near the Kth atom in atom 2, searches for
                                 another pair with the (K + 1)th atom in atom 2
                           2. Are results and K being used properly?
                               - **results**;
                                    - Is it being re-initialized (emptied) after each time KNN fails to find the
                                       cluster?
                                    - Is it returned empty if:
                                            - query never finds a pair
                                            - KNN fails every time it tries to find the rest of the atom 2 cluster
                               - **K**:
                                    - Is it only being incremented after KNN fails? (As it should)
                                    - Does it return an empty results
