I assume this matches other examples?

@marcoskirsch I assume this matches other examples?

The option string default now aligns with other driver examples. However I do not see other drivers making resource name as required input. I made it required here mainly to catch it if its missing, at the example level itself instead of letting driver initialize error out.

I think you should stay consistent. If you think making the resource name required, then make the change consistently in another PR. But I think many drivers allow leaving resource name blank in cases of simulation so that's probably why it's not required.

Made the resource name to be not required to be consistent with other driver examples. Made the resource name default value to be PXI1Slot2 to be consistent with other driver examples.
