// # Yocto/SceneIO: Tiny library for Yocto/Scene input and output
//
// Yocto/SceneIO provides loading and saving functionality for scenes
// in Yocto/GL. We support a simple to use YAML format, PLY, OBJ and glTF.
// The YAML serialization is a straight copy of the in-memory scene data.
// To speed up testing, we also support a binary format that is a dump of
// the current scene. This format should not be use for archival though.
//
// Error reporting is done through exceptions using the `io_error` exception.
//
// ## Scene Loading and Saving
//
// 1. load a scene with `load_scene()` and save it with `save_scene()`
//
