Refactor generate-at-breakpoints into functions to simplify it.

[AlecRaeside]

The complexity of the generate-at-breakpoints mixin should be refactored by moving functionality into single purpose functions which should be unit testable.

Agree, ideas?.

And can you make sure to label it based on the relevant part of Scally? I've done this one.

[AlecRaeside]

With moving logic into functions, do you think they should live the same file as the main mixin or in the functions folder? @chris-pearce

[chris-pearce]

I think the same file as the mixin if they're only relevant to that mixin, if there's reuse elsewhere then move into the functions folder.

@AlecRaeside you still keen to do this?

@AlecRaeside you still think you'll do this? If not can you close.
