Simulation under FBD model

The class beast.app.simulators.Simulator simulates a tree under the fossilised birth-death model with given parameters as programme arguments. The six arguments are: net diversification rate, turnover rate, sampling proportion, sampling at present proportion (rho), and time of origin.

The resulting tree together with sampled node ages, parameters and other features of the tree is written to trees_and_pars.txt.
