Binary Random-Access lists. All functions have the standard running times from Data.Edison.Seq except the following:

- lcons, lhead, ltail*, lview*, rhead*, size, lookup*, update, adjust, drop
`O( log n )`

- copy, inBounds
`O( i )`

- append, reverseOnto
`O( n1 + log n2 )`

- take, splitAt
`O( i + log n )`

- subseq
`O( log n + len )`

- zip
`O( min( n1, n2 ) + log max( n1, n2 ) )`
