-/** CPP-API: The Importer class forms an C++ interface to the functionality of the
-*   Open Asset Import Library.
-*
-* Create an object of this class and call ReadFile() to import a file.
-* If the import succeeds, the function returns a pointer to the imported data.
-* The data remains property of the object, it is intended to be accessed
-* read-only. The imported data will be destroyed along with the Importer
-* object. If the import fails, ReadFile() returns a nullptr pointer. In this
-* case you can retrieve a human-readable error description be calling
-* GetErrorString(). You can call ReadFile() multiple times with a single Importer
-* instance. Actually, constructing Importer objects involves quite many
-* allocations and may take some time, so it's better to reuse them as often as
-* possible.
-*
-* If you need the Importer to do custom file handling to access the files,
-* implement IOSystem and IOStream and supply an instance of your custom
-* IOSystem implementation by calling SetIOHandler() before calling ReadFile().
-* If you do not assign a custion IO handler, a default handler using the
-* standard C++ IO logic will be used.
-*
-* @note One Importer instance is not thread-safe. If you use multiple
-* threads for loading, each thread should maintain its own Importer instance.
