Struct Window 

pub struct Window {
    pub from: usize,
    pub count: usize,
    pub rev: bool,
}

Where a run of members starts, how long it is, and which way it goes.

This is what every range command reduces to, and it is a rank rather than a pair of members because the tree answers in ranks. from is the first member the walk hands over, so on a reverse walk it is the high end and the walk counts down.

Fields

from: usize

The rank the walk starts at.

count: usize

How many members the walk hands over.

rev: bool

Whether the walk counts down.
