triggers vs hooks

[appetrosyan]

Minor point about language. A smart-contract is a simple "on trigger execute Executable" concept. A trigger is the mechanism that decides that something needs to run, not the thing whose main you're calling.

In other words, iroha_trigger makes me think that the trigger isn't just the event-driven system that launched the smartcontract, but that it is the smart-contract.

The old naming convention was somewhat generic, I admit, but it wasn't conceptually dissonant.

    iroha_hook::info!("Executing trigger");

or maybe

    iroha_smartcontract::info!("Executing trigger");

Personally prefer the hook name, because it's shorter and makes it clear that it acts like lisp hooks do, minus the dynamic typing.

I'm not sure what is the difference between a hook and a trigger. If someone can explain we can consider renaming, although I find that trigger is quite adequate naming

I don't like changing terminology without good reason.
