Identify if a contract or a contract item is created from a CSV import.

Other records in NetSuite have a source field that would identify how they are created. That field is not available in a contract and contract item record. Alternatively, users can you use the system notes to identify the source. A contract that is created by saving a sales order and contract item that is generated after running the R03 script have the Set by column reflected as -System- under the system notes tab of each record. If the records are done through CSV Import, then the Set By column should reflect the user who performed the import.
