+tinyobj notes
+=============
+
+tinyobjloader-c is not a very well-documented library, so i'm gonna keep some notes
+as i figure things out
+
+ * the indices within a vertex_index_t object are not indices into the vertices, normals, or texcoords arrays;
+   rather, they are indices to 3-vectors within those arrays. To get actual indices, multiply them by three.
+ * "shapes" are individual meshes.
+   * a shape's `face_offset` is the *number of faces* into the `faces` array to go before
+     you find the data for the current shape, and the length is the *number of faces*.
+     This means that they are **NOT** indices to the `faces` array; they are indices/lengths
+     in the `face_num_verts` array, which you can then use to determine indices into the
+     faces array.
