+This test conflates a group of overlapping townhouses with another. Since the houses are adjoining, we need to be more picky about match 
+criteria. In the case where a ref building matches two secondary buildings given the model output, we match only to the one with the most 
+overlap and throw the other match out (overlap ties result in reviews). In this output, each of the six matching buildings should conflate
+with one another.
