Speed up with compiler optimization

In case anyone is clustering large datasets:

in my experiments (40M corpus and NofClusters=1000), turning on compiler optimization with "-O3" yields speed-ups of around 3.

I changed the following lines in my Makefile:

wcluster: $(files)
    g++ -Wall -g -O3 -o wcluster $(files)

%.o: %.cc
    g++ -Wall -g -O3 -o $@ -c $<

I'm surprised I didn't have it in there before. It's added now - thanks
for the note!
