Returns true if the point is contained inside the box. The point is considered to be inside the box
if the following test passes for each dimension.  box.x &le; point.x {@code <} box.x + box.lengthX

@param box Box
@param point Point which is tested to see if it is inside the box
@return true for inside and false for not
