interior angles and sorting issue

[mayakraft]

interior angles doesn't sort the inputs by clockwise/counter

const interior_angles = function (...vectors) {

[mayakraft]

this is maybe not a problem with code but with design.

in core/radial.js there is a new empty method

const interior_angles_unsorted = function (...vectors) { }

if we write this we need to get a feeling if this is even a good approach. some methods are returning indices of the arrays for sorting order, especially for use with graphs. if we shuffle things around we want to convey the new order somehow so we're looking at returning 2 different things, which is what i'm hung up on.
