[Investigation]: do we need a function that returns all events emitted by all contracts?

[0xNeshi]

What is the feature you would like to see?

From #34 (comment):

Wdyt should we create a function that returns a list of all events emitted by all contracts during a test run?

This seems like a useful feature to me, though I can't think of a use case that couldn't be tested without this 🤔

Maybe one use case would be a factory contract that creates many other contracts, that in turn emit some events?
The dev could write a test case that asserts something like "invoke factory::create(1000) (creates 1000 other contracts that each emit an event), then get a list of all emitted events and assert there are exactly 1000 of them and each is of type Event". The assertion could be made differently - get list of addresses of 1000 created contracts -> assert each contract emitted Event.

Either way, having the function shouldn't hurt motsu, we could treat it is a shorthand utility in case devs need it.

Interested in your thoughts.
