Phylogeny

[MaximilianPi]

I got a question from a user how to include a phylogenetic distance matrix. At some point we have to finally tackle this problem. At the moment I can think of two options: a) phylogenetic distance matrix as a kind of species-species "prior" on the env weights b) treat phylogenetic eigenvectors as traits and fit a fourth-corner-model (as they do in the gllvm pkg: see )
