This is partially resolved by re-writing the class for the 1D master element.
It still remains to re-organize the 2D and 3D master elements for the same purpose, which will make additional tutorials.
This is now done for 2D triangles with barycentric coords functions.
Warped nodes for 2D triangles now done.
This method is horrifying and needs to be split up / cleaned up. For one thing, there should be an option to shift the points or not. Doing complicated geometric shifts by default is not ideal -- many use cases involve low order schemes where this is totally unnecessary. Note that the reasoning for moving these points is that it prevents the Vandermonde matrix from becoming ill-conditioned at high order.
