 In:
   W   - Positive weights descibing the relative
         probabilities of particles. Can be a numeric
         array or a cell array containing particle structures.
         The weights do not not need to sum to unity.
   alg - Algorithm index. Currently only "simple"
         algorithm as index 1 is defined.      (optional, default 1)

 Out:
   ind - Indices of resampled particles. There may be multiple
         indices and some of them might be missing, but that is
         the whole idea of resampling.
