Multiple functions per event

[lkarlslund]

I forked your project, and added multiple functions per event. Also I introduced interfaces for Event and Function, which improves speed and adds functionality.

The only breaking change is that calling Fire(...) now returns [][]reflect.Value() instead of []reflect.Value()

Also the return channel is closed after functions complete.

I suggest you look at it at https://github.com/lkarlslund/go-trigger and give feedback.

This looks okay. would you mind update docs, adding some tests and sending a PR and lets have a review.

This has been a while, any update on this?

Should I just use the fork?

Sorry, I've not maintained my external version of the package for a while. The one I'm using internally is not release ready.
