[galib] PSO and galib

Hello all,

I don't know much about particle swarm, but it does not really use variation
operators.  Applying operators such as mutation and crossover does not
really make sense since PSO isn't based on evolution.  Course and velocity
are in fact deterministically ajusted at each step, weighed by a random
factor (an acceleration).

In fact it looks quite simple to code, so I would suggest implementing
it straigthforwardly.
