Integrating the Header Files

The file Partitioning.h belongs in the following directory: $LINK_BASE/include/LINK/algorithm. Note that if this were a graph generating algorithm, its files would belong in the generator subdirectory instead of algorithm (and similarly, graph layout algorithm files belong in the layout subdirectory). Once the header file has been moved to the appropriate place, the file Make.inclalgorithm should be updated to include Partitioning.h in the ``FILES.h'' macro therein to keep a record of its existance. While in the algorithms directory, we must add a prototype for our new algorithm to the file Algorithms.h.
