* @Descr: Returns the the first intersection with an object between two positions
* @Author: Ruthberg
/*
* Author: Ruthberg
* Returns the the first intersection with terrain between two positions. @todo rewrite using lineIntersectsSurfaces?

* @Arguments: [position PositionASL, position PositionASL, accuracy FLOAT]
* @Return: [intersects BOOL, intersection PositionASL]
* @PublicAPI: true
* Arguments:
* 0: PositionASL <ARRAY>
* 1: PositionATL <ARRAY>
* 2: Accuracy <NUMBER>
*
* Return Value:
* 0: Intersects <BOOL>
* 1: Intersection Position ASL <ARRAY>
*
* Public: Yes
