Support param calls with event_dim in minipyro example

[eb8680]

There is at least one test in pyroapi that uses nested plates with manual dim arguments.

This exercises some nontrivial effect handler behavior, so after #8 lands, we should update our minipyro implementation to make those tests pass.

I think we already implement nested plates - the test you linked works. Do you mean the event_dim argument?

[eb8680]

plate doesn't take an event_dim argument, so I thought your comment was referring to the dim argument of plate. Did you mean the event_dim argument of param, or something else?

[rvs314]

Yes - that's what I meant. I can start looking at implementing the event_dim parameter of param if you think that'd be useful

[eb8680]

Ah, OK. I don't think that's as interesting in terms of exercising effectful functionality, so let's not bother for now. I'll go ahead and close this issue.
