/*
 * @file
 *
 * Working sample module to demonstrate CTools 3 plugins
 *
 * This sample module is only intended to demonstrate how external modules can
 * provide ctools plugins. There is no useful functionality, and it's only
 * intended for developers or for educational use.
 *
 * As far as possible, everything is kept very simple, not exercising all of
 * the capabilities of CTools or Panels.
 *
 * Although the ctools documentation suggests that strict naming conventions
 * be followed, this code attempts to follow only the conventions which are
 * required (the hooks), in order to demonstrate the difference. You can
 * certainly use the conventions, but it's important to know the difference
 * between a convention and a requirement.
 *
 * The advanced_help module is required, because both CTools and this module
 * provide help that way.
 *
 * There is a demonstration panel provided at /ctools_plugin_example/123
