Trait poloto::iter::DoubleIterator

pub trait DoubleIterator: Iterator {
    type Next: Iterator<Item = Self::Item>;
    fn finish_first(self) -> Self::Next;
}

The trait that plot functions accept. All plots must be iterated through twice. Once to find the right scale to fit all the plots in the graph. And a second time to scale all the plots by the scale we found on the first iteration. A DoubleIterator is itself an iterator that represents its first iteration. Once that is done, the user can call finish_first to produce the second iterator.
