This function estimates ancestral character states, and the associated
can be fitted by maximum likelihood (the default, Schluter et
al. 1997), least squares (\code{method = "pic"}, Felsenstein 1985), or
generalized least squares (\code{method = "GLS"}, Martins and Hansen

- correlation structure with the option \code{corStruct}.
