AddCompany is similar to how we added insuree at the Init step. Chaincode can register brokers and insurers through this function. The company type can be a broker or insurer, as follows:

func (c *ClaimContract) AddCompany(stub shim.ChaincodeStubInterface, args []string) pb.Response {
         id := args[0]
         name := args[1]
         companyType := args[2]
         companyData := Company{
                 Id:   id,
                 Type: companyType,
                 Name: name}
         companyBytes, _ := json.Marshal(companyData)
         stub.PutState(id, companyBytes)
         return shim.Success(companyBytes)
}
