* refactor get_block_generator() to prepare for easier composing of a layered blockchain class * make get_block_generator() part of the interface to the blockchain rather than an independent, free function passed in the validation. This keeps the view of the blockchain more focused to a single class. * add test for get_block_generator * add unit test for Blockchain.lookup_block_generators() * address review comments * address review comments
