\description{
  Internal function for \code{\link{UniFrac}}.
}
\details{
  A modified version of the \code{\link{internal2tips}}
  function, such that when a tip is provided as
  \code{int.node}, that tip is returned. This is a more
  intuitive behavior than the original picante version,
  which returns NULL. This is currently used in
  \code{\link{UniFrac}}.
