> Various improvements can be made to validating the signatures and type usages in DoFns. Some things that should probably be checked:
>  * Check that StartBundle and FinishBundle contain any emit parameters and side inputs present in ProcessElement
>  * Check that any side inputs/emits have correctly matching types between Start/FinishBundle and ProcessElement
>  * Check that parameters and return values for the various methods are valid (for ex. Teardown/Setup should have no params)
