Simulates nested phylogenetic trees (gene trees in species tree, symbiont trees in host trees) using birth-death processes and transfers between lineages. Simulations of gene trees within species trees are performed using a three-tree model with species trees, locus trees, and gene trees. The cophylogenetic birth-death process is used to simulate sets of host and symbiont trees with extant associations between tips. For more information about the three-tree model see: Mallo et al.
