Implementation work started again

* Read the PAMPAS paper in the reading group. It is interesting, and just loopy with some particle filters, essentially.

* Found some issues related to initialization, apparently, since Gibbs sampler produces different results if it is run after a Tree_Gibbs_Sampler. This is because, probably, the potentials on the nodes, instead of being Constant, are left equal to something...

* Implemented FFBS for Discrete cases and pairwise case. Has to be tested

* Verified that Peter explanation on FFBS has some errors.

-> correct the inialization issues

-> lots of code clean ups ?
