Add iterator interface to that returns structs for each event.

It might be nice to a struct for stacks, an then split it into reader, collapse, 'renderer'

That would allow not having to convert a stack to a string and then back from a string to data to render flame graphs and also generalize the rendering logic.

Are you thinking of something like #30 ?

Abselutely, sorry the topic didn't give it away :) I'll comment on that.
