Sample testcase to run:

1. To register a node:

       {
           "M1": {
               "name": "Manufacturer1",
               "type": "Manufacturer"
           },
           "d2": {
               "name": "Distributor2",
               "type": "distributor",
               "id": "D2",
               "property": ["normal-chair", "office-chair"]
           },
           "c1": {
               "name": "Client1",
               "type": "client",
               "id": "C1"
           },
       }

2. To add a new Transaction:

   {
       "sender":"d1",
       "client":"c1",
       "product":"wood",
       "amount":20
   }
