mapping (uint => Proposals) public proposalInfo;		   	Proposal id => proposal information (available from outside)
mapping (bytes => bool) isProposalExist;				Whether the proposal exists

addProposal(bytes newproposal)

• (4)Vote by proposal id,true means yes, false means no

voteThoughId(uint id, bool isOk) 

• (5)To obtain whether a proposal is passed, yes is greater than no, and more than half of the 51 nodes vote yes (i.e., yes is greater than or equal to 26).

isProposalPassed(uint id)

• (6)ets the creation time of a proposal

• (7)To find out if an address has proposal and voting rights

getAddrIsAuthority(address addr)
