For T0198, we had fold-recognition alignments to various all-alpha
proteins, but none of them were a convincing model for the whole
protein, so we ended up folding this one pretty much from scratch.

We ended up with two main hypotheses:
	an up-down bundle
	an alpha sandwich

Another, slightly different bundle is try8-opt2. It does not break the
helices badly, but it packs them poorly,  with several of the helices
turned so that their hydrophobic sides are exposed.
