    address: PublicAddress,
    method_name: &str,
    arguments: Vec<u8>,
    value: u64,
) -> Option<T>

A call to contract. The caller should already know the data type of return value from the function call. It returns Option of T where T is return value from the function. If data type T is different from the actual return value type of the function, None is returned.
