intersect for box and line or segment doesn't exist #30

Box isn't a shape inside the intersect method for either segment or line. So passing a box to their intersect method fails.

I didn't see anywhere the intersectLine2Box(line, box) function was exported. Though its used internally.

I took the three function: intersectLine2Box, intersectSegment2Line and intersectLine2Line: They work for what I'm doing..

Great library! thanks for all your work!

Support intersection with box added in v1.0.19. Now method intersect(shape) supports shape of type Box for Line, Segment, Arc and Circle. Method return array of intersection points. Intersection between Polygon and Box will be added later.
