improve the thoroughness of TestPhyloXMLTreeWriter

This test now compares its output against a baseline .xml file.

add baseline directory

Forgot to add the new Baseline directory for IO/Infovis tests.
Hopefully this fixes my failing TestPhyloXMLTreeWriter test.

get the baseline file's path from the command line

This is an improvement over our previous approach of constructing
the path to the baseilne file from the testing directory.
