GO 1.8 SQL features
see #52
NOTE: in v1.2.0 sqlmock.Rows has changed to struct from interface, if you were using any type references to that
interface, you will need to switch it to a pointer struct type. Also, sqlmock.Rows were used to implement driver.Rows
interface, which was not required or useful for mocking and was removed. Hope it will not cause issues.
