A function to visualize a multi-optimum OU process evolving on a phylogeny
plotOUtreesim(pars, tree, ptsperunit = 100, pal = rainbow, aph = 255, lwd = 1)
**No return value**, called for **side effects**. The function **generates a plot** showing the simulated trait evolution over time.

A phylogenetic tree
A number giving the number of points to simulate per unit time
A color palette function
