Creating the Constants Object

Create a Constants object to keep some values. You can refer to variables across the operator while making it easier to maintain and update.

1. Add the following code:

   object OperatorConstants {
       val parameterID = "parameterId"
   }

2. Optional: Add any other variables to track.
   To reference them in the code, call OperatorConstants.parameterID.

   Note: You will see this call throughout the rest of the code in this tutorial.
