Update CBC model in same order as others + add burnin templates
In the EvolveParameters loop the CBC parameters of the same model as updated in the intrinsic/extrinsic updates for that iteration is updated. (i.e, model chain->index[ic] instead of model ic). However, in doing this PTMCMC doesn't seem to like thing anymore. Only running this with a single chain. And I am looking into getting chain swaps working correctly again. This commit also adds the CBC templates from the burnin so they can be used in he first iteration of evolve extrinsic/ intrinsic parametes.
