-// Function: vnf_get_vertex()
-// Usage:
-//   vvnf = vnf_get_vertex(vnf, p);
-// Description:
-//   Finds the index number of the given vertex point `p` in the given VNF structure `vnf`.
-//   If said point does not already exist in the VNF vertex list, it is added to the returned VNF.
-//   Returns: `[INDEX, VNF]` where INDEX is the index of the point in the returned VNF's vertex list,
-//   and VNF is the possibly modified new VNF structure.  If `p` is given as a list of points, then
-//   the returned INDEX will be a list of indices.
-// Arguments:
-//   vnf = The VNF structue to get the point index from.
-//   p = The point, or list of points to get the index of.
-// Example:
-//   vnf1 = vnf_get_vertex(p=[3,5,8]);  // Returns: [0, [[[3,5,8]],[]]]
-//   vnf2 = vnf_get_vertex(vnf1, p=[3,2,1]);  // Returns: [1, [[[3,5,8],[3,2,1]],[]]]
-//   vnf3 = vnf_get_vertex(vnf2, p=[3,5,8]);  // Returns: [0, [[[3,5,8],[3,2,1]],[]]]
-//   vnf4 = vnf_get_vertex(vnf3, p=[[1,3,2],[3,2,1]]);  // Returns: [[1,2], [[[3,5,8],[3,2,1],[1,3,2]],[]]]
