+Unlike most tests, this is actually not meant as much for unit-testing, but more like performance-testing.
+Compile this project in Release mode, then run it in folder that has NetherFort.cubeset prefabs, too, using
+a higher number of repetitions (each repetition takes time on the order of a second); investigate the
+runtime performance with a profiler.
+
+The syntax to execute this test:
+PieceGeneratorBFSTreeTest [<numRepetitions>]
+numRepetitions is the number of NetherFort structures to be generated (default = 1)
