* Enable vm_tests, remove usage of from keyword as a variable name
* Fix Genesis types and use the new EthTime
* Add a new VMKind enum (py-evm vmclass runtime type)
* renaming block_obj to block_types
* chain.BlockHeader and utils.header.Header are the same thing (BlockHeader in py-evm)
* For now blockNumbers are UInt256
* EoD merge: vm_test compiles and does not throw computation error
* running full transactions is too early
