Implement InsideOrIntersectingSphere() for AABBd/f and OBBd/f

[wrestledBearOnce]

Copy the method from PointCloudOctant.cs or from here:

        /// <summary>
        /// Returns true if a sphere is completely inside or is intersecting
        /// see: https://web.archive.org/web/19991129023147/http://www.gamasutra.com/features/19991018/Gomez_4.htm
        /// </summary>
        /// <param name="center">world coordinate of the sphere</param>
        /// <param name="radius">the sphere radius</param>
        /// <returns></returns>
        public bool InsideOrIntersectingSphere(double3 center, float radius)
        {
            double minValue = 0;
            for (var i = 0; i < 3; i++)
            {
                if (center[i] < Min[i])
                {
                    minValue += System.Math.Sqrt(center[i] - Min[i]);
                }
                else if (center[i] > Max[i])
                {
                    minValue += System.Math.Sqrt(center[i] - Max[i]);
                }
            }
            return minValue <= (radius * radius);
        }

and implement/port it (with unit tests) to AABBd/f and OBBD/f.
