They stole my question. [question?id=5669859816898560 ]
But that is ok. Given none solved it there - it feels good to solve someone else's question.

The answer :
1. From the point P, connect every vertex-node ( triangulate it )
2. This would make n triangle. Sum those areas, call it : E
3. Use two of the existing nodes as base and triangulate the polygon.
4. Sum the triangles and then we have the area of the triangle call it - A

When A == E , we have the Point inside the Polygon.
If not - then, well... you know it is not.
