-//        fish case: ensure that spinal axis of fish is the x-axis of the tile
+// TO DO:
+// - real anneal
+// - solve self-intersection problem
+// - get a better test model?
+// - symmetry constraints withing the tile
+// - rotation matrices
+// - overbinding results in forced equational constraints on the leader
+// - shatter in invertd-triforce pattern brian mentioned

+// - rotational alignment
+
