Implemented rpc server method GetRawTransaction (#135) * Added utility function GetVarSize * 1) Added Size method: this implied that Fixed8 implements now the serializable interface. 2) Added few arithmetic operation (Add, Sub, div): this will be used to calculated networkfeeand feePerByte. Changed return value of the Value() method to int instead of int64. Modified fixed8_test accordingly. * Implemented Size or MarshalJSON method. - Structs accepting the Size method implement the serializable interface. - Structs accepting the MarshalJSON method implements the customized json marshaller interface. * Added fee calculation * Implemented rcp server method GetRawTransaction * Updated Tests * Fixed: 1) NewFixed8 will accept as input int64 2) race condition affecting configDeafault, blockchainDefault * Simplified Size calculation * 1) Removed global variable blockchainDefault, configDefault 2) Extended Blockchainer interface to include the methods: References, FeePerByte, SystemFee, NetworkFee 3) Deleted fee_test.go, fee.go. Moved corresponding methods to blockchain_test.go and blockchain.go respectively 4) Amended tx_raw_output.go * Simplified GetVarSize Method * Replaced ValueAtAndType with ValueWithType * Cosmetic changes + Added test case getrawtransaction_7 * Clean up Print statement * Filled up keys * Aligned verbose logic with the C#-neo implementation * Implemented @Kim requests Refactor server_test.go * Small fixes * Fixed verbose logic Added more tests Cosmetic changes * Replaced assert.NoError with require.NoError * Fixed tests by adding context.Background() as argument * Fixed tests
