Enhancement: add plugins

[mostfunkyduck]

Have you considered writing a plugin interface for cassowary? I make a lot of use of wrk because of that capability and it's really useful. (That could totally solve #15 without having to add any flags or anything like that, as long as there's a hook point in the right place). Would love to have that here because the feature set and metrics that you've got are far superior.

I wouldn't mind taking a shot at it, if that's the direction you want this project to go. Just say the word.

Hi @mostfunkyduck,
Thanks for the input. The idea with plugins is indeed very compelling. I've been quite slow adding new features to cassowary lately since it's quite feature complete based on my needs. However as I see it cassowary is more of a community project so I am always open to add new features based on community wishes and a plugin system would totally be a good interface for that.

You are more than welcome to take a stab at this!
