Function elipdotter::set::deduplicate

pub fn deduplicate<T: PartialEq, I: Iterator<Item = T>>(
    iter: I
) -> Deduplicate<T, I, fn(_: T, _: T) -> T> 

Removes consecutive duplicate items.

This works best for sorted iterators (e.g. std::collections::BTreeMap::iter) as they always have any duplicate items right after each other.

All the iterators used within elipdotter are sorted.
