// Description:
// Produces a vnf from an array of points where each row length can differ from the adjacent rows by up to 2 in length. This enables
// the construction of triangular VNF patches. The resulting VNF can be wrapped along the rows by setting `row_wrap` to true.
// You cannot wrap columns: if you need to do that you'll need to combine two VNF arrays that share edges.
// Arguments:
// points = List of point lists for each row
// row_wrap = If true then add faces connecting the first row and last row. These rows must differ by at most 2 in length.
// reverse = Set this to reverse the direction of the faces
// Example(3D): Each row has one more point than the preceeding one.
