Remove need for init

[asbjornu]

Right not it's necessary to invoke .init() to initialize components. As discussed on Slack, Bootstrap does not require this, so we shouldn't either.

As per now the only time you NEED to run the init functions manually is if you are building a SPA. With regular routing the components will initialize themselves.

But I agree that this should be fixed for SPA's as well. I am looking into a solution for that

As an intermediate improvement, you could consider noting in the docs for which components you would need to manually invoke .init().
