This is a minor update improving/ fixing a few things.

- Segment Overlap functions fixed.

- Quad ContainsPoint function fixed. (typo was the problem)

- Polyline improvements / clean up.

- RangeFloat and RangeInt deprecated. Both classes are still available but will be removed in a future update

- ValueRange and ValueRangeInt readonly structs implemented to replace RangeFloat and RangeInt classes. They do basically the same but they are readonly structs now.
