transform_pars

Function to transform pars in a way that is more
useful for optimization: trpars &lt;- sign(pars) * pars/(sign(pars) + pars);

Implements maximum likelihood and bootstrap methods based on
the diversity-dependent birth-death process to test whether
speciation or extinction are diversity-dependent, under various
models including various types of key innovations.
