intersects

intersects([2,5],[3,6]) => true
intersects([2,5],[9,10]) => false

includes - checks if first segment includes second

includes([2,10],[3,6]) => true
includes([2,null],[3,null]) => true
includes([2,10],[9,null]) => false

containsPoint

containsPoint([1,5],4) => true
containsPoint([1,null],4) => true

union

union([1,5],[2,6]) => [1,6]
union([1,5],[6,7]) => null

intersection

intersection([1,5],[4,6]) => [4,5]
intersection([1,5],[4,null]) => [4,5]
intersection([null,5],[4,null]) => [4,5]

mask - masks first segment with array of other segments

mask([1,10],[[null,2],[5,6],[9,15]]) => [[1,2],[5,6],[9,10]]
