new-relayer-standard

currently i am busy with promethon
but i am gonna add better doc, nounce support, address mapping support and some other things to this later

road map

create the standard version 1 to 3
create the standard version 4
write script that can automatically rewrite and compiles contract with this standard
write golang code for relayer
write js code for relayer
write react code for relayer client

let us all look for a solution that can fix the bug proposed in the contract relayer04 for double calling in the given scenario
