docs: Check if a given point is inside a polygon.
  
      Parameters vertices_x[] and vertices_y[] define the polygon.
      The number of array elements is equal to number of vertices of the polygon.
      This function works for convex and concave polygons.
  
      Parameters
      ----------
      vertices_x, vertices_y : lists or arrays of floats
          Vertices that define the polygon.
  
      x, y : float
          Coordinates of the point to check.
  
      Returns
      -------
      inside : bool
          `True` if the point is inside the polygon.
