 I am unable to replicate the results of Monteiro & Burer, 2004.  This may
 mean that the Augmented Lagrangian algorithm itself has a bug in it (which
 I suspect), or simply that my implementation of the Lovasz-Theta SDP is
 incorrect (which I suspect slightly less).

 When this is solved, tests should be working for:

  * johnson8-4-4
  * hamming6-4
  * keller4

 Runtime may be too long on those, so maybe we'll only run one each time,
 but before this is resolved all those tests need to work.
