I think this is definitely needed in boost::random, and it seems to do  
much more error checking and dealing with large weights than my  
version does, so I will definitely change to using it once it makes it  
into a normal library release (and I can persuade my HPC admin to  
upgrade the library)

I think you should rename it categorical distribution though as it  
only samples a single trial from the distribution. I believe the  
multinomial distribution gives the probability of vectors arising when  
n trials are performed.

Thanks,
