Dtest

Conducts correlational D-test from stochastic mapping

This function conducts the 'D-test' of Huelsenbeck et al. (2003).

Dtest(t1, t2, nsim=100, ...)

`t1`	set of stochastic map trees (i.e., object of class `"multiSimmap"` for character 1. Note that `t1` and `t2` should be of the same length.
`t2`	set of stochastic map trees (i.e., object of class `"multiSimmap"` for character 2. Note that `t1` and `t2` should be of the same length.
`nsim`	number of simulations to use in the test.
`...`	arguments to be passed internally to `make.simmap`. Note that (for now) these must be the same for both `t1` and `t2` (that is to say, we are not able to assume different trait evolution models for each tree).

Note that this function has been included without much testing, and so the user should be wary.

An object of class "Dtest".
