For now, a single sample input will be special-cased in the EM model - but that will change when the EM model degenerates to the single sample output with a single sample as input. For now, the EM code for multi-samples isn't finished; I'm planning on checking that in soon.
The SingleSampleIntegrationTest now uses the UnifiedCaller instead of SSG, and so should all of you. More on that in a separate email.
Other minor cleanups added too.
