Use the new entropy function for precomputation
Mike Hughes
FIX two bugs in ELBO calculation are fixed. First, elbo_alloc() function replaced with elbo_alloc__forloop, which correctly does the normalization constant of the prior for every branch. Second, E-step for VB now does row-wise matrix-vector addition, not col-wise...

Fix calculating respPair
Mike Hughes
TEST found a failing test with N=3 nodes, K=2 comps and non-uniform likelihood. looks like the respPair calculation is broken. Other tests indicate that resp is off slightly in some cases too.
