Pull request overview
Adds a new NI-SWITCH community example script demonstrating individual relay control (open/close) on a switch module, with a small CLI wrapper and simulated-run tests consistent with other examples in this repo.
Changes:
- Introduces
niswitch_individual_relay.pyexample with CLI arguments for resource name, topology, relay, action, simulate, and reset behavior. - Implements a minimal “example / _main / main” structure plus
test_example()andtest_main()for simulated execution.
