00008  * NestedLoopFilter implements Filter using a simple nested
00009  * loop algorithm.  This is not supposed to be efficient.  It is our
00010  * baseline implementation against which we check the correctness and
00011  * compare the efficiency of other implementations.  It's not advisable
00012  * to run this filter on large data sets.
