Should perform some computation, but allow one to specify A, C, T after the fact, as well as the vcov function. This is somewhat complicated: it would carry the theta matrix, as well as a lm object over which the vcov could be applied later. We would have to refactor the theta code, however, to avoid repeating ourselves.
