KataRange

Range has a lot of nifty issues.

• integer range contains

[2,6) contains {2,4}

[2,6) doesn't contain {-1,1,6,10}

• getAllPoints?

[2,6) allPoints = {2,3,4,5}

• ContainsRange?

[2,5) doesn't contain [7,10)

[2,5) doesn't contain [3,10)

[3,5) doesn't contain [2,10)

[2,10) contains [3,5]

[3,5] contains [3,5)

• endPoints

[2,6) allPoints = {2,3,4,5}

[2,6] allPoints = {2,3,4,5,6}

(2,6) allPoints = {3,4,5}

(2,6] allPoints = {3,4,5,6}

• overlapsRange

[2,5) doesn't overlap with [7,10)

[2,10) overlaps with [3,5)

[3,5) overlaps with [3,5)

[2,5) overlaps with [3,10)

[3,5) overlaps with [2,10)

• Equals

[3,5) equals [3,5)

[2,10) neq [3,5)

[2,5) neq [3,10)

[3,5) neq [2,10)
