* Added new config attributes: 'SecondsPerBlock','LowPriorityThreshold' * Added new files: * Added new method: CompareTo * Fixed empty Slice case * Added new methods: LessThan, GreaterThan, Equal, CompareTo * Added new method: InputIntersection * Added MaxTransactionSize, GroupOutputByAssetID * Added ned method: ScriptHash * Added new method: IsDoubleSpend * Refactor blockchainer, Added Feer interface, Verify and GetMemPool method * 1) Added MemPool 2) Added new methods to satisfy the blockchainer interface: IsLowPriority, Verify, GetMemPool * Added new methods: RelayTxn, RelayDirectly * Fixed tests * Implemented RPC server method sendrawtransaction * Refactor getrawtransaction, sendrawtransaction in separate methods * Moved 'secondsPerBlock' to config file * Implemented Kim suggestions: 1) Fixed data race issues 2) refactor Verify method 3) Get rid of unused InputIntersection method due to refactoring Verify method 4) Fixed bug in https://github.com/CityOfZion/neo-go/pull/174#discussion_r264108135 5) minor simplications of the code * Fixed minor issues related to 1) space 2) getter methods do not need pointer on the receiver 3) error message 4) refactoring CompareTo method in uint256.go * Fixed small issues * Use sync.RWMutex instead of sync.Mutex * Refined (R)Lock/(R)Unlock * return error instead of bool in Verify methods
