The subcontract management process of the semipublic chain.

	pragma solidity ^0.4.11;
	contract semiPublicControl {
	//Set up new address of Subcontract, only the Commander has authority
	function setSubcontract Address(address_address) external onlyCommander {
	Subcontract = Subcontract Interface(_address);}//Set up new address of Contract, only the Commander has authority
	function setNewcontract Address(address addressnew) external onlyCommander {address Newcontract = addressnew;}}
