Goal

Simplify how edges are generated
- This is currently the most unweildy part of the codebase
Add unit tests to confirm functionality

How are edges generated

In shape_base, edges are cahced in the cache_edges function
if possible to build edges, _build_edges is called

Classes

SS2D_IndexMap

Maps index ranges to an object

Rename the file this class is defined in

Change from meta_mat_to_idxs.gd
index_map.gd

build_edges(shape_material, bool)

Should remove boolean parameter
- Child classes should overrride if they want to wrap around
Should add parameter that takes verticies(?)
- If so, can make function static / move it elsewhere
- Cannot inherit then though
Gets index_mappings using get_meta_material_index_mapping
iterates through each index_mapping
- Builds an SS2D_Edge with _build_edge_with_material for each index_mapping

get_meta_material_index_mapping

Is passed verts as a parameter
- if wrap around is desired, should push_back the first vert
Returns an array of SS2D_IndexMaps
- Each indexMap should be contiguous and map to a meta_material

_build_edge_with /without _material

This is where a lot of complexity lies that I would like to remove
Make one function instead of two
Allow passing null for the material
Remove wrap_around parameter
