This interface has a read-only property for each parameter on the job it represents. It is generally
 published as parameters (where it represents the parameters of the current job), or chainParameters
 (where it represents the parameters of the current chain).
 The value of the property is the input value of the specified property. It is not possible to assign
 to these values.
 Examples:
 
   - parameters.Company - the input value of the parameter 'Company' on the current job.
- chainParameters.BusinessUnit - the input value of the parameter 'BusinessUnit' on the current job.
