-* Re-enable the exact volume tests. Should probably occur after I
- figure out why each tetrahedron doesn't have 1/24th the volume of
- the cube.
+* Update show definitions.
-* Add exact area tests for the remaining tetrahedron.
+* Document everything.
-* Add the rest of the edge incidence tests.
+* Test whether or not dropping the guards from the Tetrahedron.volume
+ function speeds things up (and still produces a correct result).
+
+* Re-run hpc and remove any dead code.
