This function simulates the evolution of a continuous character along a
phylogeny. The calculation is done recursively from the root. See
- Paradis (2006, p. 151) for a brief introduction.
+ Paradis (2012, pp. 232 and 324) for an introduction.

\details{
There are three possibilities to specify \code{model}:
\code{alpha}, and \code{theta}. This may be interesting for the last
one to model varying phenotypic optima. The exact updating formula
from Gillespie (1996) are used which are reduced to BM formula if
- \code{alpha = 0}.
+ \code{alpha = 0}.}
\item{A function:}{it must be of the form \code{foo(x, l)} where
\code{x} is the trait of the ancestor and \code{l} is the branch
Ornstein-Uhlenbeck process and its integral. \emph{Physical Review E},
