/** @file Exporter.cpp

Assimp export interface. While it's public interface bears many similarities
to the import interface (in fact, it is largely symmetric), the internal
implementations differs a lot. Exporters are considered stateless and are
simple callbacks which we maintain in a global list along with their
description strings.

Here we implement only the C++ interface (Assimp::Exporter).
