Function makeTacosAndTortillas

makeTacosAndTortillas(graph, epsilon?): {
    taco_taco: TacoTacoConstraint[];
    taco_tortilla: TacoTortillaConstraint[];
    tortilla_tortilla: TortillaTortillaConstraint[];
}
Parameters
- graph: FOLDExtended
  a FOLD object. vertices_coords should already be folded.
- Optional epsilon: number = EPSILON
  an optional epsilon with a default value of 1e-6
Returns {
    taco_taco: TacoTacoConstraint[];
    taco_tortilla: TacoTortillaConstraint[];
    tortilla_tortilla: TortillaTortillaConstraint[];
}
For a particular model, a set of layer constraints sorted into taco/tortilla/transitivity types needed to be solved.
- taco_taco: TacoTacoConstraint[]
- taco_tortilla: TacoTortillaConstraint[]
- tortilla_tortilla: TortillaTortillaConstraint[]
Description
Given a FOLD object, find all instances of edges overlapping which classify as taco/tortillas to determine layer order.

Notes
due to the face_center calculation to determine face-edge sidedness, this is currently hardcoded to only work with convex polygons.
