splitter_memory.patch 

This patch reduces memory requirement in splitter by ~50% by replacing class
SparseInt2ShortMultiMap with class Node2AreaMap. 
It also includes small performance tweaks.

Still not solved by this patch:
- Memory usage depends on the highest node id in the data.
- Node id > Integer.MAX_VALUE do not work (not a problem at this moment)

If this small patch is okay for you, I can provide a bigger one that also
fixes these issues, but touches many more files

Ciao,
Gerd
