 * Here is a smaller test tree that you can easily draw by hand (or use the web visualization link). Note that both TreeViewX and the web drawing tool draw the left and right branches from the parent's perspective (looking from the root towards the leaves)

 Average distance: 20.8 Min distance/node [16.0, 'b'] Max distance/node [30.0, 'c']  (where I did average distance the equal-weighting way, and the root branch was included) (I think if you do it the "phylogenetic-weighting" way the avgDist comes out to 22.375 but I'm too tired to double-check)
 * Your code, run with this example tree, should give the answers below (which hopefully match what you get when you do it by hand )
