`project_folder`	the folder when you want to save data and results
`sim_pars`	vector of starting parameters: sim_pars[1] is lambda, the sympatric speciation rate; sim_pars[2] is mu, the extinction rate; sim_pars[3] is nu, the multiple allopatric speciation trigger rate; sim_pars[4] is q, the single-lineage speciation probability;
`optim_ids`	ids of the parameters you want to optimize.
`cond`	sets the conditioning cond = 0: no conditioning; cond = 1: conditioning on stem or crown age and non-extinction of the phylogeny;
`n_0`	the number of lineages at time equals zero.
`t_0s`	starting time for each clade
`seed`	the seed
`sim`	the results of a sim run
`results`	mle results
