    contract StorageCell{

        string _storageHash;
        string _storageInfo;
        string version;

        constructor (string storageHash, string storageInfo) public {
           _storageHash = storageHash;

        }

        function getStorageCell() public constant returns(string, string){

            return(_storageHash,_storageInfo);
        }

        function getVersion()constant returns(string){
            return version;
