The docs say `points` must be a (N, 2) array. You pass a (2, ) array. Make it: ``skimage.measure.points_in_poly(np.array([[0,0]]),cont2)``

Hi everyone,
I would like to use the function points_in_poly to test if the point x,y is in the contour cont2 x=0 y=0, but I have the problem with any value of x and y:
skimage.measure.points_in_poly(np.array([x,y]),cont2) where cont2 is a contour of type array : but I get the following error: "IndexError: invalid index"
it is a little obscure for me, is there a problem with this function, or is it me who don't know how to apply it ?
thanks a lot!
Julien
