/**
 * Import models into manifoldCAD.
 *
 * ManifoldCAD uses [gltf-transform](https://gltf-transform.dev/) internally to
 * represent scenes. Importers must convert their models to in-memory
 * gltf-transform Documents.
 *
 * The high level functions `importModel()` and `importManifold()` will import
 * models as display-only and full manifold objects respectively.  These
 * functions are available in manifoldCAD.
 *
 * @packageDocumentation
 * @group ManifoldCAD
 * @category Input/Output
 * @groupDescription Low Level Functions
 * These functions are not available within manifoldCAD, but can be used when
 * including manifold in another project.
