Pesto currently accepts and reads in trees even if they are non-binary, or have negative branch lengths. I guess this is fine, however, before making an SSEdata object, we should verify that:
Branch lengths are non-negative (done)
The tree is binary (each speciation event has two descendant lineages, not more or fewer)
