25test that the rotational physics is correct.
26
27an "anchor body" has a number of other randomly positioned bodies
28("particles") attached to it by ball-and-socket joints, giving it some
29random effective inertia tensor. the effective inertia matrix is calculated,
30and then this inertia is assigned to another "test" body. a random torque is
31applied to both bodies and the difference in angular velocity and orientation
32is observed after a number of iterations.
33
34typical errors for each test cycle are about 1e-5 ... 1e-4.

25test the Coulomb friction approximation.
26
27a 10x10 array of boxes is made, each of which rests on the ground.
28a horizantal force is applied to each box to try and get it to slide.
29box[i][j] has a mass (i+1)*MASS and a force (j+1)*FORCE. by the Coloumb
30friction model, the box should only slide if the force is greater than MU
31times the contact normal force, i.e.
32
33 f > MU * body_mass * GRAVITY
34 (j+1)*FORCE > MU * (i+1)*MASS * GRAVITY
35 (j+1) > (i+1) * (MU*MASS*GRAVITY/FORCE)
36 (j+1) > (i+1) * k
37
38this should be independent of the number of contact points, as N contact
39points will each have 1/N'th the normal force but the pushing force will
40have to overcome N contacts. the constants are chosen so that k=1.
41thus you should see a triangle made of half the bodies in the array start to
42slide.

31if a test number is given then that specific test is performed, otherwise
32all the tests are performed. the tests are numbered `xxyy', where xx
33corresponds to the joint type and yy is the sub-test number. not every
34number maps to an actual test.

37 i: the test is interactive.
38 g: turn off graphical display (can't use this with `i').
39 e: turn on occasional error perturbations
40 n: performe test XXX
41some tests compute and display error values. these values are scaled so
42<1 is good and >1 is bad. other tests just show graphical results which
