// Usage:

|

// Description:
|
||||
// Takes an edge set descriptor and returns the edges array representing those edges.
|
||||
// This function is useful for modules that take `edges` arguments, like `cuboid()`.
|
||||
// An edge set descriptor can be any of:
|
||||
// - A vector pointing towards an edge, indicating just that edge.
|
||||
// - A vector pointing towards a face, indicating all edges surrounding that face.
|
||||
// - A vector pointing towards a corner, indicating all edges that meet at that corner.
|
||||
// - The string `"X"`, indicating all X axis aligned edges.
|
||||
// - The string `"Y"`, indicating all Y axis aligned edges.
|
||||
// - The string `"Z"`, indicating all Z axis aligned edges.
|
||||
// - The string `"ALL"`, indicating all edges.
|
||||
// - The string `"NONE"`, indicating no edges at all.
|
||||
// - A raw edges array, where each edge is represented by a 1 or a 0. The edge ordering is:
|
||||
// ```
|
||||
// [
|
||||
// [Y-Z-, Y+Z-, Y-Z+, Y+Z+],

// [X-Z-, X+Z-, X-Z+, X+Z+],
