 In order to implement this enhancement the following changes should be made in the MapServer codebase:
    
-1) Expose the functions treeNodeCreate and treeAddShapeId from maptree.c to allow using the quadtree
-   implementation during the clustering process.
-2) Modify the lexer to interpret the connection types (COMBINE and CLUSTER).
-3) Implement mapcombine.c containing the code of the combine layer data source.
-4) Implement mapcluster.c containing the code of the cluster layer data source.
