[development] update node_example.module to use schema api

I notice that the file node_example.module on http://api.drupal.org/api/file/developer/examples/node_example.module has not been upgraded to show how to use the schema api. I am interested in updating this page, which has been so helpful to me, to include a hook_schema implementation and some drupal_write_record calls. How and where is this documentation stored? What is the best way for me to make my proposed changes so they can be reviewed by the community and maintainer? Thanks Jon
